RCT-YES is a free software tool that allows you to easily analyse data and report results on the effectiveness of programs in your context. RCT-YES can help you figure out "what works" in any policy field. You can use the free software for many research designs--including the most rigorous random assignment design--as long as a comparison group exists.

This tool guides educational researchers through defining an inference population, selecting important sample characteristics, developing a recruitment plan for a future evaluation, and determining the generalizability of a completed evaluation.

PowerUp! allows you to determine the optimal sample size needed to achieve specified minimum detectable effect sizes and to calculate the minimum detectable effect size for a specified level of statistical power and precision. It also produces tables of the assumptions and estimates generated by the application.

This software includes a series of empirical estimates of plausible parameter values for determining the minimum effect size that can be detected by a given number, size, and treatment/group mix of randomized groups.

The Institute for Politics Research database provides empirical estimates of design parameters for two and three-level cluster randomized trials that use academic achievement as an outcome variable. These estimates are available for the nation as a whole and for selected states.

This tool is designed to facilitate the estimation of costs and cost-effectiveness of educational or other social programs. It is designed for researchers, analysts, educational administrators, and policymakers, but it is free for anyone to use it.
