Application of Best Linear Prediction and Penalized Best Linear Prediction to ETS Tests

This is the authors' abstract. We don't add key points for this paper.

Best linear prediction (BLP) and penalized best linear prediction (PBLP) are techniques for combining sources of information to produce task scores, section scores, and composite test scores. The report examines issues to consider in operational implementation of BLP and PBLP in testing programs administered by ETS.
