mox: we have been hearing for months that the Avi Chai study proves a 3.5% growth rate. Now we see that it only discovered ~2% if you count all Orthodox schools or if you count Yeshiva and half of centrist. Only with original and creative methods can you squeeze out 3.2%, and I have explained that newly DISCOVERED small schools could account for that blip. Additionally, SJ demonstrated on the previous page that if you try different permutations of comparing grades you can easily find negligible growth.
So I stand by my statement that the hard numbers undermine the “age gap” theory.
