Working with Youth Futures

IFF is an evaluation partner for our What Works programme testing youth employment interventions.

Overview

This Statistical Analysis Plan (SAP) sets out the predefined analytical methods for evaluating the Summer Jobs Programme, a six‑week youth employment intervention delivered by UK Youth through Local Delivery Partners (LDPs).

The evaluation is a two‑arm, multi‑site randomised controlled trial with individual‑level randomisation stratified by LDP. Eligible and consenting young people who complete right‑to‑work checks are allocated 1:1 to either the intervention group (offered Summer Jobs) or the control group (receiving business‑as‑usual support).

The trial consists of a Year 2 Internal Pilot Study (2025) followed by a Year 3 Efficacy Study (2026).

The purpose of the analyses described is to estimate the impact of being offered Summer Jobs on prespecified co‑primary outcomes (offending and EET status), secondary survey‑based outcomes, and exploratory subgroup effects, using an intention‑to‑treat framework.

This document outlines the statistical models, handling of missing data, adjustments for multiplicity, and planned sensitivity and robustness checks.

A full description of the intervention, implementation model, trial procedures, and outcome measures is available in the Summer Jobs Trial Protocol.
