Three algorithms for selecting a subset of originally available items to maximize coefficient alpha, including one advanced by Serlin and Kaiser (1976), were compared on the size of the resulting alpha and computation time required with nine sets of data. Results indicated that a combination of the two alternate algorithms proposed would perform better than the Serlin-Kaiser method. The characteristics of a computer program to perform these item analyses are described.
