The edTPA® Handbooks are not novels, but you really should read through the WHOLE Handbook before you do anything else.
As you read, highlight terms that aren’t clear. Then, look in the glossary to see if those terms are defined. If they’re not, use a dictionary! This will ensure that you understand the academic language of the edTPA® assessment.
And, of course, make sure that you have the latest version of the Handbook!
