This lacks sophistication as a blog entry. But it does give me a chance to post information in an interesting way. The data is from the Grade 5 statewide mastery test. It only spans 3 years because the science test has only been given that long. Not sure what to make of it except for variability in changes between schools and from one year to the next. These particular schools (all pseudonyms) were chose because half had high achievement gaps in science (by Students of Color, % ELLs and low income families) and the other have had smaller gaps — not that anyone (even me!) can tell which is which from this display.
