What researchers studied

Randomized controlled trial of a 3.6-fold scale-up of an online mathematics tutoring program implemented by regional education authorities in Navarre, Spain. 1,344 vulnerable students across 46 public schools in Navarre, Spain, randomized to online mathematics tutoring or a control condition

What they found

  • Assignment to tutoring increased standardized mathematics scores by 0.11 standard deviations and transcript math grades by 0.15 standard deviations.
  • The scaled effects were about 30 to 42 percent of the original pilot effects.
  • Students reported higher math self-efficacy and lower anxiety, although survey attrition makes these estimates less certain.
  • An enhanced social and emotional training module improved affective outcomes but did not add academic gains.
  • The study did not detect a meaningful difference between groups of two and three students per tutor, but it lacked power to rule out modest differences.

What the study does not prove

  • Outcomes were measured immediately after the eight-week program, so the persistence of gains is unknown.
  • Survey attrition and nonresponse introduce uncertainty around social and emotional outcomes.
  • The trial involved vulnerable students in one Spanish region and may not generalize to other systems, ages, or tutoring models.
  • The group-size comparison was underpowered for modest differences and should not be treated as proof that larger groups are equally effective.
  • The program used qualified interim public-school teachers, so the results do not apply to every online tutoring workforce.

Evidence strength: Randomized controlled trial with administrative grades and standardized assessments under government implementation; short follow-up, survey attrition, and one-region context limit generalization; working paper.

Why this matters for families

Do not ask only whether a tutoring model is evidence-based. Ask how it is delivered, monitored, and adjusted for your child.

Noor interpretation

How Noor translates the evidence into practice

A successful pilot is not a finished operating system. When tutoring grows, educator selection, training, attendance, group size, instructional alignment, and quality monitoring can change the result.

Noor Lyra can use research-backed methods while still monitoring the individual learner, the educator match, session quality, attendance, practice, and evidence of progress. The method matters, and so does the delivery.

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.
