Procedures previously recommended by various authors for the estimation of scores, residual or basefree measures of change, and other kinds of difference scores are examined. A procedure proposed by Lord is extended to obtain more precise estimates, and an alternative to the Tucker-Damarin-Messick procedure is offered.
