What researchers studied

Randomized evaluation across grades in 48 public primary schools in Pune, India, testing a model that recruited college STEM fellows and supported them with training, instructional coaching, and lesson scripts while they partly replaced regular math and science teachers. Students and instructional staff across 48 public primary schools in Pune, India; the intervention recruited college students in science, technology, engineering, and mathematics fields as teaching fellows

What they found

  • Although fellows had less formal education and teaching experience than regular teachers, they scored 1.56 standard deviations higher on an assessment of content knowledge and pedagogy.
  • After one year, the intervention increased student achievement by 0.32 standard deviations in math, 0.23 standard deviations in science, and 0.16 standard deviations in language.
  • Math and science gains persisted three months later, and effects extended beyond items that could plausibly have been directly coached.
  • Fellows used stronger pedagogical practices, and fellows with greater knowledge adhered more closely to substantive components of the lesson scripts, suggesting that structured pedagogical supports complemented rather than substituted for expertise.

What the study does not prove

  • This is a 2026 EdWorkingPaper and should not be described as a peer-reviewed journal article unless a later published version is independently verified.
  • The intervention combined several elements at once: selective recruitment for subject expertise, training, coaching, lesson scripts, and partial replacement of regular teachers. The student gains cannot be attributed to any single component in isolation.
  • The study took place in public primary schools in Pune, India, so effect sizes should not be generalized to U.S. private tutoring, other school systems, older students, or different subject areas.
  • The fellows were not private tutors, and the findings do not establish that younger or less experienced educators are generally more effective than veteran teachers.

Evidence strength: Strong experimental evidence; randomized evaluation across 48 schools; EdWorkingPaper.

Why this matters for families

Families should look beyond a resume line that simply says how many years someone has taught. This randomized study suggests that strong subject knowledge paired with strong instructional support can matter substantially, although the exact effects belong to this specific school-based program in India and should not be treated as a promise about private tutoring outcomes.

Noor interpretation

How Noor translates the evidence into practice

The study supports a Noor Lyra principle: educator quality is not captured by years of experience alone. Demonstrated subject knowledge matters, and its value can be amplified by a structured instructional system that includes coaching, clear teaching routines, and support for translating expertise into student understanding.

For Noor Lyra Educators, hiring and development should assess more than credentials or tenure. Subject mastery should be demonstrated directly, and educators should be supported with the Noor Method, coaching, progress evidence, and clear instructional expectations so expertise consistently becomes effective teaching behavior.

No single study determines a student's plan. Noor uses research as one input alongside the learner's goals, observed performance, academic context, and response to instruction.
