What NYSED says about assessing it

Clarification statement

Emphasis should be on the distinction between coding and non-coding regions of DNA.

The three dimensions

Every item written to HS-LS3-1 has to assess all three dimensions together, not the content alone. This is the structural change that made older practice material stop matching the exam.

Science & engineering practice
