The FHA Roster Appraiser must sign the certification of the appraisal and perform all parts of the analysis and reconciliation. Appraiser trainees or licensees may not sign the appraisal report. A trainee or licensee may assist in any part of the appraisal, but the opinions and analysis must be performed by the FHA Roster Appraiser. A trainee or licensee may accompany the FHA Roster Appraiser on the observations but may not perform the observations in place of the FHA Roster Appraiser.
