Abstract : As part of a continuing program for estimating the relation of true score to observed score, three new models were tried out, using data from many large-scale testing programs. The first model produced results of practical value for perhaps half of the sets of data. Two generalizations of the first model, without encouraging outcome, are summarized in appendices. (Author)
