I know West Chester in Pennsylvania takes students in the Spring. Although it's not very well known outside of Pennsylvania it's actually a pretty dedicated program from what I have gotten from the program director - Dr.C.
Also, there is a linkage to Drexel and to Temple and you are still eligibile for linkages even if you begin in the Spring - however, it wouldn't be for the following Fall but the next one if that makes any sense. Aslo you must complete all pre-req's at WC if you want to be considered for linkage.
Anyway, check it out.
