“Most colleges have said that they will use the College Board concordance tables to compare old SAT and new SAT scores.”
Do you think this is true? I did a tour last month of some mid-Atlantic and Southeastern private Unis and asked this specific question. Nobody said that they would follow the Concordance Tables. The responses came basically in 2 categories: 1) These are different tests (old SAT and new SAT) so we will evaluate you on how well you did on the test that you actually took so we are ignoring the concordance tables or 2) We have a holistic process and SAT/ACTs are much less important than GPA, rigour of schedule and essays.
Therefore, I think that many public universities (excluding the top ones that claim to be holistic) will use the concordance tables as they have large numbers of applications to get through and many of their merit scholarships are GPA and SAT/ACT focused, but that many private schools will not and will formulate their own criteria.
