Job Evaluation Methods Compared: Point Factor, Ranking, and Market Pricing

The Core Design Challenge

Whole-job ranking is the simplest methodology: jobs are ordered from least to most complex based on the overall judgement of an evaluation panel. It requires no formal scheme, no training beyond a shared understanding of the organisation's work, and produces results quickly. For organisations with fewer than 50 roles that are relatively similar in nature, it is entirely adequate. Its limitation is its subjectivity: when roles are diverse, complex, or numerous, ranking becomes unreliable — different evaluators produce different orders, and no structured basis exists for resolving the disagreement. It is also the methodology most vulnerable to challenge in equal pay litigation, because the reasoning behind each ranking decision is not documented in a way that can be independently verified.

Point-factor evaluation is the methodology used by most large organisations because it is the most analytically defensible. A defined set of compensable factors — typically covering knowledge and expertise, problem-solving complexity, accountability and impact, and communication requirements — is applied to each role, with each factor scored on a defined scale with point values assigned to each level. The total points for a role produce a score that can be compared across all roles in a single consistent framework. The defensibility comes from the documentation: every factor, every level, and every score is recorded, and the reasoning for each decision is explicit rather than implicit. In equal pay proceedings, a well-documented point-factor evaluation is far easier to defend than a ranking or a title-based comparison.

Market pricing replaces internal evaluation with external reference data — a role is priced by matching it to the survey job that most closely resembles it and using the survey percentile data to set the pay level. It is externally grounded and fast, but it produces no internal equity framework: two roles with very similar complexity and accountability may be priced very differently simply because one has a well-established survey job and the other doesn't. Market pricing is most useful as a calibration check on internally evaluated ranges, not as a substitute for evaluation. The organisation that uses only market pricing has a competitive compensation system and no internal equity architecture.

How the Approach Works

Most organisations in practice use a hybrid: point-factor evaluation produces grade placements; market data calibrates the salary ranges within those grades. This is the approach that delivers both internal equity (consistent evaluation across all roles) and market competitiveness (ranges anchored to actual market data). The design complexity is in building a point-factor scheme that is specific enough to produce consistent results but simple enough for a trained panel to apply without specialist statistical knowledge — typically four to six factors with four to eight levels each is the working range for most organisations.

Calibration is the step that converts a theoretically sound methodology into a practically consistent one. Without calibration — agreed examples for each factor level, anchor roles that the panel has scored together, and a process for resolving panel disagreements — the same scheme applied by two different panels will produce different results for the same role. This is not a methodology failure; it is a calibration failure. The methodology provides the structure; calibration provides the shared interpretation that makes the structure produce consistent outputs.
