Try a sample question
An NGO compares graduates of its voluntary training programme with people who did not enrol and finds graduates earn more. The main threat to concluding the programme caused the gain is
- the programme's curriculum having been changed during the first year
- too many graduates answering the follow-up survey for valid analysis
- selection bias, since motivated people may be more likely to enrol and earn more anyway
- measurement error caused by rounding incomes to the nearest hundred dollars

What does the Impact Evaluation & RCT Design Certification cover?
Five skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Evaluation Foundations (Theory of change, The counterfactual and Evaluation questions); Randomised Designs (Randomisation strategies, Units and stratification and Power); Quasi-Experimental Methods (Difference-in-differences, Regression discontinuity and Instrumental variables and matching); Implementation, Analysis and Reporting (Attrition and spillovers, Pre-analysis plans and Reporting standards); Ethics, Cost-Effectiveness and Policy Use (Research ethics, Cost-effectiveness and Using evidence).

Law, IR and public-policy students at Yale, Georgetown, Sciences Po, LSE and SAIS want practice-ready skills without government or bar exams. Passing earns a founder-signed Science of Apps certificate with a credential ID and QR code that recruiters can verify.
Why are randomised controlled trials considered strong evidence of impact?
Random assignment makes treatment and comparison groups statistically similar on average in both observed and unobserved characteristics, so differences in outcomes can be attributed to the programme rather than to selection bias.
When should I use a quasi-experimental method instead of an RCT?
When randomisation is impossible, unethical or too late, methods such as difference-in-differences, regression discontinuity or instrumental variables can estimate impacts, but each relies on assumptions such as parallel trends or no manipulation at a cutoff that must be argued and tested.
Can I take the Impact Evaluation & RCT Design Certification from any country?
Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.
