The Comprehensive Final Exam covers all Reading & Study material for the course. The exam is
open-book/open-notes and contains 50 questions requiring calculations and interpretations of
data and test/assessment material that teachers would likely encounter in the classroom. The
exam has no time limit and is to be submitted as a Microsoft Word document through the
appropriate submission link. Fill in the blanks as appropriate; for multiple-choice questions,
identify your response by circling, underlining, highlighting, or marking with an asterisk.
