Pairwise comparison scale extension using core linking sets

Pairwise comparisons can be used to equate two sets of educational performances. In this article, a simple method for the joint scaling or more assessment performances is described and illustrated. This applicable where scale student abilities has already been formed, extended include additional It requires subset scaled performances, which designated as core linking set purpose extension. The article illustrates application construct with larger range latent abilities, using fewer compared standard pairwise comparisons. design differs from in way are paired. pairing also efficiently place individual on an existing scale.
