Overview
People is one of three HR knowledge domains in the 2026 SHRM BASK and carries 19% of the SHRM-SCP. It holds five functional areas: HR Strategy, Talent Acquisition, Employee Engagement & Retention, Learning & Development, and Total Rewards. Together they cover how the organization plans its workforce, attracts and selects talent, keeps people engaged, builds their capabilities and rewards them.
For the SCP, the emphasis is on system design and alignment rather than transactions: building the workforce plan that follows from business strategy, choosing whether to build, buy or borrow talent, setting a pay philosophy, and checking that each program produces measurable results without disparate impact. The 2026 BASK expands proficiency indicators and key concepts across HR Expertise and adds AI examples, which shows up most visibly in AI-assisted hiring.
How it's tested
People items mix HR-specific knowledge questions, such as definitions, formulas and model stages, with situational judgment items about designing or fixing talent programs. Expect calculations such as compa-ratio, turnover and selection-rate ratios, and scenarios that ask which strategy or measure best supports a stated business goal.
-
Strategy-to-program alignment
A business goal is stated, such as entering a market or cutting costs, and you choose the talent strategy that serves it, for example building, buying or borrowing skills.
-
Apply the formula or model
You calculate compa-ratio, turnover or the four-fifths ratio, or identify the ADDIE phase or Kirkpatrick level a scenario describes.
-
Diagnose a people problem
Turnover, engagement or pay-equity data reveals a problem, and you choose the analysis or intervention that addresses its root cause.
A company must add AI engineering skills within six months for a product launch, and the internal talent pipeline is thin. Options include an 18-month internal academy, hiring experienced engineers, or contracting specialists while building internal capability. Reasoning: the timeline rules out building alone, so buy or borrow now and build for the longer term. The strongest answer blends contractors or hires for the launch with a development track that reduces dependence later.
Functional areas 5
Official functional areas from the SHRM outline, in outline order.
4.1 HR StrategyTurning business strategy into workforce plans, priorities and measures.
- What it means
- HR Strategy covers environmental scanning, aligning HR goals with organizational strategy, workforce planning and measuring HR's contribution. At the SCP level you are the one formulating the strategy, not executing it.
- What to understand
- Workforce planning compares the current workforce with the future demand implied by strategy, through a gap analysis, then closes gaps by building (developing), buying (hiring), borrowing (contractors) or redeploying talent. HR strategy should be measured with outcome metrics tied to business goals, such as time to productivity or retention of critical roles, not activity counts.
- How it shows up
- A scenario states a business strategy and asks which HR priority, workforce plan or metric best supports it.
- Common confusion
- Candidates confuse HR's mission or values statement with its strategy, or choose a best-practice program that does not serve the stated business objective.
4.2 Talent AcquisitionWorkforce sourcing, employer branding, selection and onboarding, including AI in hiring.
- What it means
- Talent Acquisition covers employer value proposition and branding, sourcing channels, selection methods, offers and onboarding. The 2026 BASK adds AI examples, such as AI screening and sourcing tools and the need to audit them for bias.
- What to understand
- Structured interviews and work samples have stronger predictive validity than unstructured interviews. Any selection tool, including an algorithm, must be checked for adverse impact, commonly screened with the four-fifths rule: a group's selection rate below 80% of the highest group's rate signals possible adverse impact.
- How it shows up
- A scenario gives selection-rate data or describes a new AI screening tool and asks what HR should conclude or do.
- Common confusion
- Assuming a vendor's AI tool is compliant because it does not use protected characteristics directly, when proxies such as zip code or employment gaps can still produce adverse impact.
4.3 Employee Engagement & RetentionMeasuring engagement, managing turnover and keeping critical talent.
- What it means
- This functional area covers engagement surveys, recognition, performance management practices, retention strategy and turnover analysis, with attention to the employee experience and the role of managers.
- What to understand
- Turnover rate equals separations during a period divided by average headcount for the period. Separate voluntary from involuntary and regrettable from non-regrettable turnover, and use stay interviews and engagement data to act before people leave, since exit interviews explain only after the fact.
- How it shows up
- Data shows rising turnover in a segment, and you choose the analysis or intervention that targets the cause.
- Common confusion
- Treating engagement and satisfaction as the same thing; a satisfied employee can be comfortable but not committed or willing to give discretionary effort.
4.4 Learning & DevelopmentNeeds assessment, program design, delivery, evaluation and career development.
- What it means
- L&D covers analyzing learning needs, designing and delivering programs, evaluating results, and building career paths, leadership pipelines and succession plans.
- What to understand
- ADDIE (analysis, design, development, implementation, evaluation) starts with a needs assessment at organizational, task and individual levels. Kirkpatrick evaluates at four levels: reaction, learning, behavior and results, and training is the wrong answer when the performance gap comes from tools, incentives or process.
- How it shows up
- A scenario describes a training request or a program that did not change performance, and you identify the missing ADDIE step or Kirkpatrick level.
- Common confusion
- Treating a high level 1 reaction score as evidence that training worked, when only levels 3 and 4 show behavior change and business results.
4.5 Total RewardsCompensation philosophy, pay structures, benefits and recognition.
- What it means
- Total Rewards covers pay philosophy, job evaluation, pay structures, incentives, benefits and their compliance context, and pay equity, designed to attract, retain and motivate within budget.
- What to understand
- A pay philosophy sets the market position (lead, match or lag). Compa-ratio equals pay divided by the range midpoint, and range penetration equals pay minus range minimum, divided by range spread. Pay-equity analysis compares pay for similar work while controlling for legitimate factors.
- How it shows up
- A scenario gives salary and range data or a market-position problem, and you calculate a ratio or choose a pay strategy.
- Common confusion
- Confusing compa-ratio (position against the midpoint) with range penetration (position within the range), or assuming leading the market fixes retention problems caused by managers.
High-yield concepts
The terms, rules and formulas this domain turns into questions most often.
-
Workforce planning gap analysis
Comparing the current workforce supply with the future demand that the business strategy implies, by role, skill, number and location.
- Remember
- Close gaps by building, buying, borrowing or redeploying, and match the choice to the timeline and how central the skill is.
- Tested as
- HR Strategy scenarios hinge on choosing the right gap-closing approach.
- Trap
- Choosing a long internal development program when the business needs the skill in months.
-
Four-fifths (80%) rule
Under the Uniform Guidelines on Employee Selection Procedures, a selection rate for a group below 80% of the highest group's rate is generally treated as evidence of adverse impact.
- Remember
- Selection rates of 42% and 60% give a ratio of 0.70, below 0.80, which flags possible adverse impact.
- Tested as
- Calculation and AI-in-hiring items use it directly.
- Trap
- Comparing the raw numbers hired instead of selection rates.
-
Structured interview
Every candidate gets the same job-related questions, scored against defined anchors by trained interviewers.
- Remember
- Structure improves validity and consistency and reduces bias compared with unstructured conversation.
- Tested as
- Selection-design scenarios favor structured methods.
- Trap
- Preferring unstructured interviews to judge culture fit, which invites bias.
-
AI in hiring
Using algorithms for sourcing, screening, assessment or scheduling, added as an explicit area in the 2026 BASK.
- Remember
- The employer remains responsible for adverse impact and should audit the tool, understand its criteria and keep human review.
- Tested as
- Expect scenarios about adopting or auditing an AI screening tool.
- Trap
- Relying on the vendor's assurance instead of the organization's own adverse-impact analysis.
-
Turnover rate
Separations during a period divided by average headcount in that period, times 100.
- Remember
- Segment it by voluntary versus involuntary and regrettable versus non-regrettable before acting.
- Tested as
- Metrics and retention scenarios use it.
- Trap
- Dividing by ending headcount, or treating all turnover as bad.
-
Stay interview vs. exit interview
Stay interviews ask current employees what keeps them and what might make them leave; exit interviews ask departing employees why they left.
- Remember
- Stay interviews are proactive and let managers act before the loss.
- Tested as
- Retention-strategy items ask for the best preventive tool.
- Trap
- Relying on exit data alone to fix retention.
-
Engagement vs. satisfaction
Engagement is emotional commitment and willingness to give discretionary effort; satisfaction is contentment with the job and its conditions.
- Remember
- Managers are a key driver of engagement, so act on survey results at team level.
- Tested as
- Survey-action scenarios test this distinction.
- Trap
- Running a survey and not acting on it, which lowers engagement further.
-
ADDIE
Analysis, design, development, implementation and evaluation: the standard instructional design sequence.
- Remember
- Analysis (needs assessment) comes first and can show training is not the solution.
- Tested as
- Items ask which phase was skipped or comes next.
- Trap
- Designing content before confirming a skills gap exists.
-
Kirkpatrick's four levels
Reaction, learning, behavior and results.
- Remember
- Level 3 checks on-the-job behavior change and level 4 checks business results; executives care most about level 4.
- Tested as
- Evaluation items ask which level a measure belongs to.
- Trap
- Calling a post-test score (level 2) evidence of behavior change (level 3).
-
Succession planning
Identifying critical roles and developing ready-now and ready-later successors for them.
- Remember
- Focus on critical roles and pipelines, with development plans, not just a names-on-a-chart exercise.
- Tested as
- Leadership-pipeline and risk scenarios at the SCP level.
- Trap
- Naming a single heir without developing them or a bench.
-
Compa-ratio
Employee pay divided by the midpoint of the pay range.
- Remember
- Pay of $90,000 on a $100,000 midpoint gives a compa-ratio of 0.90, below midpoint.
- Tested as
- Compensation calculations and pay-positioning scenarios.
- Trap
- Dividing by the range maximum or minimum instead of the midpoint.
-
Range penetration
Pay minus range minimum, divided by range maximum minus range minimum.
- Remember
- It shows how far through the range someone is, from 0% at the minimum to 100% at the maximum.
- Tested as
- Paired with compa-ratio in pay-administration items.
- Trap
- Treating it as identical to compa-ratio.
-
Lead, match or lag pay policy
A pay philosophy positions pay above, at or below the relevant labor market.
- Remember
- Leading costs more and helps attract scarce skills; lagging relies on other rewards, such as equity, flexibility or mission.
- Tested as
- Strategy items ask which pay position fits the business situation.
- Trap
- Assuming leading the market solves turnover driven by poor management.
-
FLSA exempt status
Under the Fair Labor Standards Act, exemption from overtime requires meeting a salary basis, a salary level and a duties test.
- Remember
- Job title alone never makes a role exempt; the duties test decides.
- Tested as
- Total rewards and classification scenarios.
- Trap
- Classifying a role as exempt because it is salaried.
Side by side
Concepts candidates mix up, compared on the point that decides the answer.
Build vs. buy vs. borrow talent
| Concept | Meaning | Key difference | Common trap |
|---|---|---|---|
| Build | Develop existing employees | Slowest, strengthens retention and culture | Choosing it for urgent skill needs |
| Buy | Hire externally | Faster, costs more, brings new perspectives | Overlooking internal candidates and the morale cost |
| Borrow | Use contractors, consultants or gig workers | Fastest and flexible, but capability leaves with them | Borrowing for core, long-term capabilities |
Compa-ratio vs. range penetration
| Concept | Meaning | Key difference | Common trap |
|---|---|---|---|
| Compa-ratio | Pay divided by range midpoint | Position relative to the market-target midpoint | Using the range maximum as denominator |
| Range penetration | (Pay minus minimum) divided by (maximum minus minimum) | Position within the whole range | Treating it as interchangeable with compa-ratio |
Kirkpatrick levels
| Concept | Meaning | Key difference | Common trap |
|---|---|---|---|
| Level 1: Reaction | Did participants find it useful and engaging? | Satisfaction survey | Using it as proof of effectiveness |
| Level 2: Learning | Did knowledge or skill increase? | Tests or demonstrations | Assuming learning means behavior changed |
| Level 3: Behavior | Do people apply it on the job? | Observation or 360 feedback after training | Skipping it because it takes longer |
| Level 4: Results | Did business outcomes improve? | Business metrics such as quality, sales or turnover | Claiming results without isolating the training's effect |
Exam traps
Each trap is an answer that looks right. Learn the clue that should change your mind.
-
Train everyone
- What candidates pick
- Launch a training program in response to a performance problem.
- Why it looks right
- Training is the most familiar HR intervention.
- Why it's wrong
- ADDIE starts with needs analysis; if the gap stems from tools, incentives, process or management, training will not fix it.
Clue to watch for Employees already know how to do the task, or the problem is limited to one team or manager.
-
Trust the vendor's AI
- What candidates pick
- Adopt an AI screening tool because the vendor certifies it as bias-free.
- Why it looks right
- Vendor assurances and automation seem to reduce risk.
- Why it's wrong
- The employer remains accountable for adverse impact; it should run its own analysis on its applicant data and keep human oversight.
Clue to watch for The scenario does not mention any internal validation or monitoring of selection rates.
-
Raise pay to fix turnover
- What candidates pick
- Move the whole pay structure to lead the market after turnover rises.
- Why it looks right
- Pay is a visible, fast lever.
- Why it's wrong
- If exits cluster under certain managers or in certain roles, the cause is likely not pay; segment the data first.
Clue to watch for Turnover is concentrated in specific teams, or exit data cites managers or growth.
-
Count heads, not rates
- What candidates pick
- Conclude there is no adverse impact because more women than men were hired.
- Why it looks right
- The raw numbers look favorable.
- Why it's wrong
- The four-fifths test compares selection rates (hires divided by applicants); a group can have more hires but a lower rate.
Clue to watch for The applicant pools for the groups differ in size.
-
Level 1 as success
- What candidates pick
- Report the leadership program as effective because participants rated it 4.8 out of 5.
- Why it looks right
- High satisfaction feels like success.
- Why it's wrong
- Reaction scores do not show behavior change or business results; executives need level 3 and 4 evidence.
Clue to watch for The question asks whether the program improved performance or justified its cost.
-
Strategy as a program list
- What candidates pick
- Present a list of best-practice HR programs as the HR strategy.
- Why it looks right
- Programs are concrete and show activity.
- Why it's wrong
- An HR strategy starts from the business strategy and workforce gaps, and sets priorities with measurable outcomes; a program list without that link is not a strategy.
Clue to watch for The scenario stresses a specific business objective, such as growth, cost or a new market.
Answer framework
Use these steps to work through a People domain question.
- Start from the stated business goal or problem and the timeline, since they determine the talent strategy that fits.
- Segment the data, such as turnover by type, team or role, or selection rates by group, before choosing an intervention.
- Apply the correct formula or model step: turnover, four-fifths ratio, compa-ratio, range penetration, an ADDIE phase or a Kirkpatrick level.
- Check the fairness and legal side of any talent decision, especially adverse impact from selection tools and pay-equity gaps.
- Choose the option that fixes the root cause and defines an outcome measure linked to the business, such as quality of hire, retention of critical roles or productivity.

Study strategy
Start with HR Strategy, because the other four functional areas follow from it: environmental scanning, workforce gap analysis and the build, buy, borrow decision frame most SCP-level People scenarios. Then study Talent Acquisition and Total Rewards, which hold most of this domain's formulas, and finish with Employee Engagement & Retention and Learning & Development.
High-priority concepts are the four-fifths rule, compa-ratio, range penetration, turnover rate, ADDIE and Kirkpatrick's levels. Learn them until you can calculate or classify without hesitation. Commonly underestimated areas are AI in hiring, which the 2026 BASK adds explicitly, and benefits basics within Total Rewards, which candidates from generalist roles often skip.
Afterwards, do timed calculation drills and then mixed situational judgment items, and for each miss note whether you skipped data segmentation or chose a familiar program over a root-cause fix. Then move to Workplace, where U.S. Employment Law & Regulations covers the discrimination, wage-hour and benefits laws behind many People decisions.
FAQ
How much of the SHRM-SCP is the People domain?
SHRM's 2026 handbook weights People at 19%, tied with the Leadership cluster as the largest weight. The weighting is the same for the SHRM-CP and SHRM-SCP.
Which formulas should I know for this domain?
At minimum: turnover rate, the four-fifths selection-rate ratio, compa-ratio and range penetration, plus being able to classify Kirkpatrick levels. ROI from the Business cluster also appears in People scenarios.
What is new for People in the 2026 BASK?
The 2026 BASK expands proficiency indicators and key concepts across the functional areas and adds AI examples. In this domain that is most visible in AI-assisted hiring and the need to audit such tools.
How does the SCP test People differently from the CP?
The functional areas are the same, but SCP scenarios ask you to set strategy, such as the workforce plan, pay philosophy or talent pipeline, rather than run the process.
Does the four-fifths rule prove discrimination?
No. It is a rule of thumb from the Uniform Guidelines that signals possible adverse impact. It triggers investigation of whether the selection procedure is job-related and whether less discriminatory alternatives exist.
How long should I study the People domain?
As a planning estimate, about 25-35 hours of a 150-hour plan. Add time to Total Rewards if you have not worked in compensation or benefits.
How does People connect to the rest of the exam?
It applies Business cluster analytics to talent decisions and relies on Workplace employment law for compliance. Organization's Workforce Management covers related planning and restructuring decisions.
