History of TaRL’s Evidence in India
Pioneered by Pratham in India, the TaRL approach has generated evidence of its impact in diverse contexts across the country.
Since 2001 the Teaching at the Right Level approach has reenvisioned classroom learning to tailor lessons to a child’s learning level rather than age. This approach has been tested in many different contexts and has been shown to improve foundational skills, allowing children to progress in their primary education.
Pratham, an Indian education NGO, began designing and implementing programmes which focused on providing children with basic skills by tailoring teaching to children’s learning levels. In 2001, Pratham partnered with J-PAL-affiliated researchers to investigate the impact of Pratham’s “Balsakhi” programme. Balsakhis (“children’s friends” – female secondary school graduates) pulled Grade 2 to 4 children who were struggling with the curriculum out of class for two hours a day to focus on basic reading and mathematics skills. The programme improved children’s learning outcomes by 0.14 standard deviations in the first year and 0.28 standard deviations in the second year. This was the beginning of a long learning partnership between Pratham and J-PAL, and the start of what we now know as Teaching at the Right Level.
Following the first impact evaluation, a series of additional impact evaluations conducted by researchers tested different delivery models and confirmed that targeted instruction can be successful when delivered through different means: by tutors, volunteers, and government teachers; and both in-school and out-of-school. Through this iterative approach to program design, key programme components have been identified and strengthened.
A paper by Banerjee et al 2016 identifies two particularly strong models of TaRL which work well at scale:
- Tutor- or volunteer-led learning TaRL camps held for periodic bursts of time were effective in Uttar Pradesh, India. This model included local instructors leading TaRL activities for 30-50 days in public schools with supplementary support in summer camps.
- Government teacher-led TaRL instruction throughout the school year was effective in Haryana, India, a state with relatively strong government systems. This intervention included dedicated time for TaRL during the school day and support for teachers through mentoring and monitoring.

Remedying Education: Evidence from Two Randomised Experiments in India (2007)
This paper presents the results of two randomised experiments conducted in schools in urban India. A remedial education program hired young women to teach students lagging behind in basic literacy and numeracy skills. It increased average test scores of all children in treatment schools by 0.28 standard deviation, mostly due to large gains experienced by children at the bottom of the test-score distribution. A computer-assisted learning program focusing on maths increased maths scores by 0.47 standard deviation. One year after the programs were over, initial gains remained significant for targeted children, but they faded to about 0.10 standard deviation. Dive into the details here.
Pitfalls of Participatory Programs: Evidence from a Randomised Evaluation in Education in India (2008)
This study explores a randomised evaluation of three interventions to encourage beneficiaries’ participation to India: providing information on existing institutions, training community members in a testing tool for children, and training volunteers to hold remedial reading camps. These interventions had no impact on community involvement, teacher effort, or learning outcomes inside the school. However, in the third intervention, youth volunteered to teach camps, and children who attended substantially improved their reading skills. This suggests that citizens face constraints in influencing public services. Explore the findings here and a J-PAL policy brief here.
Mainstreaming an Effective Intervention: Evidence from Randomised Evaluations of “Teaching at the Right Level” in India (2016)
In this study, researchers evaluate a series of efforts to scale up the NGO Pratham’s approach to teaching children according to their actual learning level, in four Indian States. While this approach was previously shown to be extremely effective when implemented with community volunteers outside of school, the objective of these new scale-up evaluations was to develop a model that could be implemented within the government school system. In the first two instances (Bihar and Uttarakhand), the methodology was not adopted by government school teachers, despite well-received training sessions and Pratham support. Motivated by the quantitative and qualitative analysis of these early attempts, the approach was adapted and large-scale experiments in the states of Haryana and Uttar Pradesh were designed to test two new scale-up models. In Haryana, teachers received support from government resource persons trained by Pratham, and implemented the approach during a dedicated hour. In Uttar Pradesh, Pratham volunteers implemented high-intensity, short-burst “learning camps” for 40 days, in school and during school hours, with additional 10-day summer camps. Both models proved effective, with gains in language of 0.15 standard deviation in Haryana, and 0.70 standard deviations in Uttar Pradesh, on all students enrolled in these schools at baseline. These two models provide blueprints that can be replicated inside other government systems. Explore the findings in detail here.
Improving Literacy and Math instruction at Scale in India’s Primary Schools: The case of Pratham’s Read India Program (2016)
Pratham’s “Read India” initiative, launched nearly a decade ago, aims to enhance basic reading and arithmetic skills in primary school children. It has evolved to employ two primary strategies. The first involves direct engagement with village communities and local schools, primarily through short-term “Learning Camps” where local volunteers help teach children in groups based on their learning levels. The second strategy is collaboration with the government, focusing on grouping children by learning level rather than grade for teaching. Both strategies have shown significant improvements in children’s learning levels, as evidenced by independent evaluations and randomised control trials. The initiative not only focuses on ground-level teaching and learning changes but also aims to shift priorities at the system level, addressing challenges in instructional change and the role of non-governmental actors in educational transformation.

From Proof of Concept to Scalable Policies: Challenges and Solutions, with an Application (2017)
In this paper, the authors describe the journey from the original concept to the design and evaluation of scalable policy by evaluating a series of strategies that aim to integrate the NGO Pratham’s “Teaching at the Right Level” methodology into elementary schools in India. Evidence is presented from randomised controlled trials involving some designs that failed to produce impacts within the regular schooling system but still helped shape subsequent versions of the program. As a result of this process, two versions of the programs were developed that successfully raised children’s learning levels using scalable models in government schools. This example draws general lessons about using randomised control trials to design scalable policies. Explore the detailed findings here.
Supporting learning in and out of school: experimental evidence from India (2022)
This paper studies an education program targeting primary school children in rural India, which combines a standard in-school pedagogical intervention with an out-of-school study group program managed by parents. We rely on a crosscutting experimental design across 200 villages and find the full program to significantly increase children’s test scores in mathematics and language by 0.09 and 0.11 standard deviations respectively. When the two program components are implemented in isolation, there is no impact on children’s learning. The cost-effectiveness analysis highlights high returns from adopting a multidimensional approach that supports children’s learning processes both in and out of school.

Using Evidence to Improve and Scale Up Development Program in Education: A case study from India (2023)
This study investigates and conceptualises how a development agency can use evidence to improve and expand its development programs, taking the case of the Indian NGO “Pratham.” In a series of experiments with researchers, Pratham developed and refined their learning agenda to search for a better strategy to improve children’s foundational learning. Pratham has also regularly conducted a nationwide survey on children’s foundational learning. Data from the nationwide survey demonstrated the problem in children’s foundational learning, and evidence from experiments showed an option for an effective strategy to address it. The search, learning, and communication cycle using data and evidence, conceptualised from the case of Pratham, would enhance the effectiveness of development agencies to better support educational development.
