The ROW Program Office will establish procedures for the continuing evaluation of PREAS contract appraisers' qualifications and performance. A

closeout evaluation

will be used as a minimum guide for evaluating the appraiser's work product at the end of each work authorization. The closeout evaluation is not parcel specific, but for the work authorization in its entirety. Aside from the closeout evaluation, an

interim evaluation

of appraiser's work product is required with every supplement to a work authorization. ROW PD may expand these forms in more detail if necessary. ROW PD should maintain sufficient information to ensure adequate qualifications of the assigned appraiser and the appraiser's capability to perform the proposed services efficiently without overload.
