This study aims to evaluate the effect of a digital waste segregation curriculum called 'Waste No More' on students of primary schools in the villages in Maharashtra, India. To establish causality, 118 schools from 52 Gram Panchayats (GPs) are randomly assigned to the treatment group who will receive the digital curriculum, while 125 schools from 53 GPs are assigned to the control group. A baseline and an end-line survey involving 1570 students from both treatment and control schools will be carried out to measure the impact of the digital curriculum on their knowledge, attitudes, and actions.

Experimental Details
The intervention consists of an 8-week interactive digital curriculum called 'Waste No More' that is designed to educate children about sustainability and waste segregation. The curriculum consists of 4 units where each unit focuses on a certain aspect of sustainability- dry and wet waste segregation, composting, recycling, etc. The curriculum follows a story-telling format for 16 episodes with animated characters. The episodes are complemented with a number of in-class and at-home activities. The curriculum is proctored by the teacher-in-charge of each treatment school. The curriculum is in the local Marathi language which is used by the Education Department of Kolhapur District, who is a key partner in the project.

Primary Outcomes (explanation)
The study will test the impact on knowledge and attitudes of the students towards waste segregation through a series of questions in the baseline and endline surveys. It will also test the changes in behavior and action of students by trying to measure waste segregation in the treatment and the control schools.

Experimental Design
Experimental Design
The experiment will be conducted across 105 Gram Panchayats (GPs) in Shahuwadi region of Kohlapur district in the state of Maharashtra, India. The study excluded 9 GPs that were in remote areas and lacked accessibility or infrastructure. The 105 GPs were randomly assigned to Treatment and Control groups. The Treatment group consists of 115 schools from 52 GPs who will receive the 8-week 'Waste No More' curriculum. The Control group consists of 128 schools from 53 GPs who will not receive the curriculum. A baseline and end-line survey will be administered with 1570 students from all the schools. For the survey, 2 students from each standard (4th-7th) will be randomly chosen, on the basis of the random generation of a roll number via a computer software.

Randomization Method
A Stratified randomization was performed, dividing the total sample of 105 Gram Panchayats into 4 strata:
Gram Panchayats with 1 school
Gram Panchayats with 2 schools
Gram Panchayats with 3 schools
Gram Panchayats with more than 3 schools.

Randomization was done within each strata through random allotment of treatment and control groups using RStudio.
Randomization Unit
The randomization unit is Gram Panchayat (GP) which is an administrative unit consisting of a group of villages.
Was the treatment clustered?
