Open the original- What it measures
- The standard treats irregular spelling as a skill to be taught at grade 1, after the regular patterns. It applies to reading, and the same words are the ones a spelling test is likely to catch.
- What it does not show
- The standard does not name the irregular words. It refers to reading, not spelling, and it does not say how many irregular words a grade 1 class should learn.
