AEH, the Crirtical Reading (CR) score threshold hasn't been 630 since they re-centered the SAT in the 1990's. 700 on CR after that re-centering corresponds to the previous 630, which is partly why the SET threshold was adjusted. Of course, the current SAT that was adopted in March 2016 is a totally different beast. The last I heard, SET is no longer relying on just the Reading score but has adopted the new EBRW score, which combines the Reading and Writing scores, but left the threshold at 700. Is it your understanding that SET is lowering the threshold to 630 for EBRW?
