Abstract
Because children spend substantial time outside school, especially during long summer breaks, a potentially scalable strategy for addressing learning loss in low-income settings is to empower parents to sustain human capital accumulation during these periods. Yet parental engagement in these settings is often suboptimal due to two key frictions: parents rarely know their child’s true ability and often lack the resources and tools to support learning effectively. We design a 2×2 factorial randomized controlled trial to test whether improving parental engagement can mitigate summer learning loss among 1,200 students in Grades 2–4 across 8 schools in Pakistan. The two cross-randomized treatments address distinct parental constraints: (1) an Information arm provides personalized diagnostic Skill Profiles revealing children’s assessed numeracy levels relative to grade expectations, targeting belief inaccuracies; and (2) a Support arm provides structured TaRL-aligned workbooks and parent training, targeting resource and capacity constraints. The combined arm tests complementarity between information and support. Our primary outcome is foundational numeracy measured by the ASER-style assessment tool. Secondary outcomes include parental belief accuracy, time and monetary investment in children’s education, and managerial behaviors. We partner with Pakistan’s leading education assessment NGO and private schools to implement this project.

Experimental Details

Interventions

Intervention(s)
This study implements a 2×2 factorial randomized controlled trial (RCT) that separates these two channels:

Information (T1): A personalized Student Math Skill Profile based on an ASER-style diagnostic assessment, showing each child’s numeracy level relative to grade expectations.

Support (T2): Structured 10-week workbooks aligned with Teaching at the Right Level (TaRL) methodology, plus a parent orientation session on how to manage daily learning activities and implement the workbook.

Combined (T3): Both Information and Support. This arm tests whether the two inputs are complements—whether knowing where the gaps are makes structured practice more effective.

Control (C): Normal summer break with no intervention.

Primary Outcomes

Primary Outcomes (end points)
Children's math score
Primary Outcomes (explanation)
An ASER-style test (20–25 minutes) will be used to assess key math competencies as outlined in the Single National Curriculum (SNC). For each grade, we will assess the child on the skills covered in the previous grade as well as the current grade curriculum.

Secondary Outcomes

Secondary Outcomes (end points)
1. Parental beliefs — Belief accuracy about the child's numeracy ability; direction of bias (over/under).

2. Parental investment and behavior — Time investment; monetary expenditure; managerial behaviors index.
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
We implement a 2×2 factorial design crossing two treatment dimensions: Information and Support.

The design is as follows: There are four groups of 300 students/parents each. The Control group receives no Information and no Support. The Info Only group receives Information (T1) but no Support. The Support Only group receives Support (T2) but no Information. The Info + Support group receives both Information and Support.

Randomization Method
Randomization is implemented in Stata.
Randomization Unit
Randomization is conducted at the individual level within ~50 strata defined by school, grade, and section (8 schools × 3 grades × ~2 sections per grade). Within each stratum, students are randomly assigned with equal probability to one of four arms.
Was the treatment clustered?
No
