HR Information Systems, Metrics, and Technology
This domain tests how HR systems capture, protect, and use workforce data. Expect questions on HRIS modules, data governance, self-service, security, and core metrics such as turnover, time-to-fill, and cost-per-hire.
Core rules
- An HRIS typically includes core employee records, payroll, benefits, time and attendance, an applicant tracking system, and a learning management system.
- Data governance defines ownership, standards, access, retention, and quality. Role-based access and audit trails protect personally identifiable information.
- Employee self-service reduces transactional work but requires identity controls and clear data-entry rules.
- Turnover rate equals separations during a period divided by average headcount, multiplied by 100. Voluntary turnover excludes retirements, layoffs, and other involuntary separations when the question asks for voluntary.
- Time-to-fill is usually days from requisition approval to offer acceptance; definitions must be consistent across reports. Cost-per-hire includes advertising, recruiter time, and other direct costs.
- Dashboards should use consistent definitions, denominators, and time periods; analytics maturity moves from reporting to prediction.
Worked example
An agency has 12 separations in a year and an average headcount of 100. Turnover is 12 divided by 100, times 100, or 12 percent. Four separations were retirements, so voluntary turnover is 8 divided by 100, or 8 percent. If HR reports time-to-fill as 45 days from posting rather than 60 days from requisition approval, the metric looks better but is not comparable to prior reports. Reasoning: define the numerator, denominator, and clock start before comparing periods or agencies.
Traps
- Using headcount instead of full-time equivalents when the metric requires FTEs.
- Counting internal transfers as separations.
- Mixing voluntary and involuntary turnover in one headline rate.
- Treating an HRIS report as accurate without checking duplicate or missing records.
