The three most important words are document, prove, and portfolio.

DOCUMENT:
This is your testimony about what happened in that course. For homeschool work, documentation is usually done through a Daily Log Book -- keep a daily log record of what was done, course-by-course. (See sample on pages 54-55.)

PROOF:
Think of yourself on the witness stand. The documentation in your Daily Log Book is your “testimony” about what happened. But as good as your testimony might be, it is not “evidence” -- testimony is only your say-so. Now we need evidence. That’s where the portfolio shines.

Make your evidence complete, convincing, and compelling for each subject. We must have some physical evidence to be convinced this work actually occurred. (More on pages 46-52.)

PORTFOLIO:
This is where the “testimony” and the “evidence” come together. Each homeschool course submitted for credit must be included in a portfolio review at the end of each year. This portfolio review will include FIVE necessary items:
1. The Daily Log Book
2. The Collection of Evidence to review
3. The Homeschool Transcript
4. The Summary Sheet
5. The check for return postage

All of this is detailed on pages 54-61 of the NARS High School Handbook.
