Subclaims¶

q3 i? An independent evaluation of New Mexico's K–3 Plus program found that when implemented with fidelity to program principles, participating students were far more likely than others to score as proficient, with the greatest positive impact on students from low-income families. → Oakes 2020 q3 i? Students enrolled in K–3 Plus in the summer prior to kindergarten were more ready for school, outperformed their peers, and continued to show higher achievement 4 years later. → Oakes 2020 (2)

Oakes, J., & Espinoza, D. (2020). Community schools the New Mexico way. Learning Policy Institute. https://learningpolicyinstitute.org/product/improving-education-new-mexico-way

q3 · i? · review · r2

Independent scientific evaluation of New Mexico's K–3 Plus expanded learning time program (25 additional summer days of reading, writing, and mathematics instruction), as described in the report. Fidelity conditions mattered; no effect sizes are printed.

"a careful evaluation of the program showed that, when it was implemented with fidelity to the program principles (e.g., having teachers teach the students they have during the regular year), participating students were far more likely than others to score as proficient, and the positive impact was greatest on students from low-income families."

q3 · i? · review · r2

The same evaluation's longer-term finding, reported in the report's evidence section: kindergarten-entry participants outperformed peers and maintained higher achievement 4 years later. No effect sizes are printed.

"an independent, scientific evaluation found that students enrolled in K–3 Plus in the summer prior to kindergarten were more ready for school and outperformed their peers. They continued to have higher levels of achievement 4 years later."

Discussion¶

Related Claims¶

• Effects were larger in intervention schools with a higher percentage of economically disadvantaged students or a lower percentage of White students — the general claim this finding bears on, with the studies behind it
• Concentrated poverty in New Mexico is associated with lower grade-level proficiency and inequitable access to experienced teachers — related
• K–3 Plus expanded learning time program showed positive impact on student learning — possibly the same claim (merge candidate)
