Will schools end use of the old SAT I for the class of 2017 after a certain date and then only accept the new SAT I?
Colleges will accept both old and new SATs
For the Class of 2017 they will accept both but class of 2018 and beyond, they will only accept new SAT
Class of '17 will be fine.
Yale, however, has announced that it will not accept the old SAT for students graduating high school in '18. It’s possible other schools may follow suit, but I haven’t heard about any doing so yet.
