The evidence will move. The site stays credible only if it moves with it, visibly.
What we are watching
| What to watch | Why it matters | Expected |
|---|---|---|
| WestEd replication of interleaved math practice(opens in a new tab) | First independent test with state test outcomes; could confirm or shrink the 61% vs 38% result | Project runs through July 2027 |
| Mississippi adolescent literacy initiative | Tests whether the state's approach works past 4th grade (Mississippi Today(opens in a new tab)) | Ongoing |
| Tutoring at scale | Nashville showed small effects; new scale-up studies will refine the design rules (Kraft et al.(opens in a new tab)) | Ongoing |
| Knowledge-building curriculum trials | Only two strong studies so far; any new trial changes principle 10's evidence file | Ongoing |
| New IES practice guides and WWC reviews | Federal reviews feed several grades | As released |
| Deans for Impact, AERO, EEF updates | New summaries from groups that review the same research | Quarterly check |
How grades change
A grade moves up only with a new randomized trial or meta-analysis of trials that meets the evidence bar, and moves down when a strong study contradicts it. Every change is logged with the date, the study, and one sentence on why. The full rules are on the evidence bar page.
