As a much younger and naive mom, our second child was applying to PEA where her brother was a current student. We had developed a relationship with our admissions officer through our sons admission process & our son had spoken at a few events in our hometown on his experience at PEA at this AO’s request. I mentioned to the AO that our daughter would be retaking the SSAT as her score was only a 93 (a few points lower then her brothers) and he was very direct that those few points were not important and not to bother retaking. Of course this doesn’t tell you the cutoff where score differences become meaningless. But I do think it is true that few points are not going to make the difference of admit or not once you pass the threshold.
