Blaich isolated 10 colleges (he said later that most but not all were liberal arts colleges) that had very similar scores on the good practices related to teaching. Their spending per student, however, ranged from $9,225 to $53,521 (with corresponding tuition rates). Others at the high end of per-student spending were at $44,429 and $34,172. Three other colleges, however, were achieving the same educational impact with spending per student of about $15,000
