What you need to know about low-cost randomized controlled trials
- Well-conducted randomized controlled trials (RCTs) are generally the most accurate way to estimate the effectiveness of a program or intervention, but they can be expensive. Low-cost RCTs greatly reduce costs by using existing data and embedding evaluations into existing programs.
- Low-cost RCTs make this type of study affordable for government agencies looking to test new approaches to policy or practice, learn what works, and increase their return on investment.
- Low-cost RCTs can complement traditional RCTs by first identifying effective programs that are then studied using more expensive RCTs.
