# Rising Academies schools: Rori AI math tutoring through WhatsApp

Students can receive adaptive, low-bandwidth math practice without a scarce one-to-one tutor.

Function: Enrollment. Patterns: Creator to judge. Evidence: verified.

Freshness: current. Reviewed: 2026-08-23. Updated: 2026-08-22.


Source quality: 1 peer reviewed; publication outcomes are verified.

## Before

1. **Student** — Attends normal math classes and studies with available static materials or limited human support. (control: School curriculum.)
2. **Teacher** — Provides class-level feedback within available time. (control: Instructional judgment.)

## After

1. **Student** — Uses a school-provided phone for two weekly WhatsApp tutoring sessions during study hall. (control: Scheduled school setting and common curriculum.)
2. **Rori and teacher** — Rori provides individualized practice and feedback while normal instruction continues unchanged. (control: Teachers and schools retain curriculum and safeguarding authority.)

## Decision rights

Teachers and schools control curriculum, access, and assessment; students interact within scheduled sessions.

## Exception path

Connectivity, comprehension, or safeguarding concerns return to teachers and normal school support.

## Outcomes

- **Mathematics growth score** (verified): Control students continued identical classes and classroom hours without Rori access. → Treatment growth was significantly higher with effect size 0.36 (p<0.001), described as roughly an extra year of learning.. Preliminary year-one evaluation; authors advise judicious interpretation.
- **Marginal delivery cost** (verified): One-to-one human tutoring is scarce and costly in the setting. → Approximately US$5 per student.. Marginal cost excludes broader school implementation and device-management costs.

## Executive lesson

A narrow, scheduled supplement can expand individualized practice without pretending to replace teachers.

## Anti-pattern

Generalizing one-year results to unsupervised home use or all subjects.

## Questions for leaders

- Does learning persist?
- Who handles misconceptions?
- What is the full implementation cost?
