Section 7 CSR 10-10.060 - Explanation of Standard Deviation Rating System for All Contractors

PURPOSE: This rule describes the procedures and rating values used in annual ratings of contractors.

(1) Statistical Analysis. Statistical analysis shall be used by the commission to compare performance by the contractors. Through standard deviation analysis, the commission shall determine how each contractor's performance compares to all others.

(2) Rating Categories. The following categories shall be used by the commission in determining the annual rating of each contractor based on their contractor performance project evaluations completed for the rated year and on the statistical analysis used by the commission: average, above average, below average, outstanding and unacceptable:

(A) Average Rating. An average rating shall result if the contractor's rating is within the range of the mean of the total population plus or minus one (1) standard deviation;

(B) Above Average Rating. An above average rating shall result if the contractor's rating is equal to or greater than the mean of the total population plus one (1) standard deviation but less than the mean plus two (2) standard deviations;

(C) Outstanding Rating. An outstanding rating shall result if the contractor's rating is equal to or greater than the mean of the total population plus two (2) standard deviations;

(D) Below Average Rating. A below average rating shall result if the contractor's rating is equal to or less than the mean of the total population minus one (1) standard deviation but greater than the mean minus two (2) standard deviations; and

(E) Unacceptable Rating. An unacceptable rating shall result if the contractor's rating is equal to or less than the mean of the total population minus two (2) standard deviations.

(3) Overall and Category Ratings. On an annual basis, each contractor who has done work for the commission and which the department has completed a contractor performance project evaluation, shall be given a rating for each of the four (4) categories: quality of work, prosecution and progress, contract compliance, and contract administration as well as receiving an overall rating which combines the ratings of all of the four (4) categories.
