The first draft of the NGSS Primary Evaluation of Essential Criteria for Alignment (PEEC-Alignment) is now available for review and feedback. This should be a useful tool for reviewing instructional materials and for modifying and creating instructional materials.
Here is a piece of text from the front matter of the document on p. 2:
First, a few words about PEEC-Alignment. The acronym is intentionally a play on words. In one sense, the evaluation is a peek, or a quick look at a program. In another sense, this document describes a peak, the highest point, principal, or most important features of NGSS-aligned programs. PEEC-Alignment is designed to achieve both of these important goals.
