OK, here is the breakdown (you can request a PDF from the Pitt OT Dept that has this exact info and final $$$ total for the program). This is specific for the OT Dept (OOS):
$7516 Summer I, $13,139 Fall I, $13,139 Spring I, $6,453 Summer II, $13,114 Fall II, $13,064 Spring II, $7,466 Summer III for a total of : $73,891. This includes tuition and fees only.
Note that the above info is for 2011-2012 (not 2012-2013).
The yearly rate of $25,388 on their web page is for two terms (Fall and Spring) and does not include summers. It also does not include mandatory fees. Mandatory fees are currently $200 for each Summer term and $370 for each Fall term and $370 for each Spring term (this is on top of tuition). Lab fees run an additional $25 to $75 a term (depending on the term).
So again, the total tuition/fees for the MOT program (based on 2011-2012 rates) is currently $73,891.
Better to know all of this info ahead of time to help out with planning.
