This is not official NSCA policy. These ideas a borne out of experience with instructing Exam Prep Symposia and having taken the exam.

1. Follow the Detailed Content Outline closely. This is your best clue as to what’s on the exam. (you'd be surprised by how many people ignore this)

2. Use the Essentials of ST&C textbook extensively (but not exclusively). This should be obvious, but again, people ignore it.

3. Cross-reference 1 and 2 (above), and find other NSCA resources to fill in the gaps. The TSAC Report is an easy win for this.

I don't think there are any secrets here, but this should serve as a good beginning.

Thinking about sitting for the TSAC-F certification exam?  What's holding YOU back?
