A pay grade defines a level within a structured pay structure. It groups jobs that have similar value and assigns them a pay range, typically with minimum, midpoint, and maximum pay. This setup lets an organization manage compensation consistently, so employees in different roles that are worth roughly the same amount fall into the same grade and share the same pay boundaries. Job evaluation is the process used to determine the relative value of jobs, not the level itself. Pay range refers to the spread within a grade, not the level that groups similar-valued jobs. Market pricing uses external market data to set pay, rather than defining internal levels.

Grouping jobs into families by function or career path with shared progression describes a job family. It means roles that involve similar duties and required skills are placed in the same family, and there’s a defined path for moving up within that family. This structure supports consistent evaluation, market pricing, and internal equity because pay and progression are aligned to a common ladder rather than to each job in isolation. The other options describe pay schemes that don't reflect this organized, ladder-based approach: paying each job with no shared progression, using a single pay scale for all roles regardless of function, or assigning pay randomly by department. In contrast, a job family concept creates a coherent framework for career growth and compensation across related roles.

Midpoint differential is the percentage difference between the midpoints of adjacent pay ranges. It measures how far apart the salary targets are from one range to the next, creating the ladder of progression within a pay structure. For example, if one range has a midpoint of $50,000 and the next adjacent range has a midpoint of $60,000, the midpoint differential is 20% because (60,000 − 50,000) / 50,000 = 0.20. This spacing helps ensure promotions yield meaningful increases and keeps pay progression consistent. It’s not the width of a range (that’s the range spread) nor the difference between the top and bottom of a single range, and it’s not the gap between market rate and midpoints.

External equity means setting pay so that what you offer for a given job aligns with what similar organizations pay. This keeps the organization competitive in attracting and retaining talent by reflecting market rates for comparable roles. It relies on market data from salary surveys and benchmarking against peers to determine pay ranges and midpoints. By focusing on the external market, you respond to labor supply conditions and industry standards. Internal equity, in contrast, looks at fairness of pay among jobs inside the organization, not how those pay levels stack up against external competitors. The other terms describe the pay structure or the overall compensation approach, rather than market competitiveness.
