Recruiting interviewer agreement calculator

Calculate observed rating range by candidate and mean absolute difference across same-candidate rater pairs with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use observed rating range by candidate and mean absolute difference across same-candidate rater pairs to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Observed rating range by candidate

Maximum−minimum supplied score for each candidate; zero with a single rating.

Mean absolute difference across same-candidate rater pairs

List every unordered distinct-interviewer pair within a candidate, then average absolute score differences over all pairs.

Exact agreement across same-candidate rater pairs (%)

Equal-score pair count/all comparable pairs×100.

Number of comparable unordered rater pairs

Sum n×(n−1)/2 within each candidate.

Candidates with fewer than two ratings

List candidates excluded from pair comparisons because only one rating was supplied.

Symbols and units
a
Ratings: candidate ID, interviewer ID, numeric rating
b
Minimum allowed rating
c
Maximum allowed rating

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • A descriptive agreement audit of supplied ratings. It is not chance-adjusted kappa, inter-rater reliability estimation, a candidate selection rule or proof of interviewer quality; no applicant ranking is produced.
