The Word Up Project teaches students words that are likely to encounter on high-stakes tests. Flocabulary's team created these word lists by first compiling words from grade-appropriate novels and basal readers (with an emphasis on Tier 2 words). The researchers then analyzed how often these vocabulary words appeared on state tests. The words that appeared most often are the ones taught in The Word Up Project.
For each reading level, our researchers looked at state tests at that level and two grade levels above. The words taught in Level Indigo (grade 5) are those words that are both found in 5th grade reading material and are most likely to appear on state tests in 5th, 6th and 7th grades.
