General Notes
A robust set of evidence-based studies undergirds UURC basic intervention models: Early Steps℠, Next Steps℠, and Higher Steps℠, as well as assessment instruments.
Study results include:
- U Steps models
- Effect sizes between 0.5 and 1.2.
- Early Steps℠
- At risk Grade 1 intervention students finished the school year averaging between G1-mid and G1-end reading level.
- 95 sessions
- Non-intervention (control) Grade 1 students averaging G1-early reading level.
- 135 standard Tier1 sessions.
- At risk Grade 1 intervention students finished the school year averaging between G1-mid and G1-end reading level.
- Next Steps℠
- Intervention students finished the school year averaging a year's growth in reading level.
- 45 sessions
- Non-intervention (control) students averaging half-year's growth in reading level.
- 100 Tier1 sessions.
- Intervention students finished the school year averaging a year's growth in reading level.
- Small group
- no significant advantage for 1:1 over 1:3.
