In the social sector, waiting years for evaluation results can mean missed opportunities. Iterative A/B testing bridges the gap between measurement and implementation delivering causal evidence in weeks, not years to improve programs as they roll out. 🧵 @ssir.org @noamangrist.bsky.social

📣 New piece on the core components of teaching at the right level combining insight from RCTs + adjacent fields + implementer views. To scale programs, we need to know their core components - what can't be removed to preserve impact & what can be removed to lower cost: www.wwhge.org/resources/co...

I only recently learned that the first significant antisemitic massacre in Europe was in France and the Rhineland, 1096 by Crusaders who took a detour on their way to the Holy Land to slaughter 2000 Jews. We keep thinking it’s past history but it never seems to be. en.wikipedia.org/wiki/Rhinela...

📢 #EdWorkingPapers: Tutoring is powerful but expensive to scale. Across 12 rapid A/B tests, @noamangrist.bsky.social, @ccullen.bsky.social, & @janicalapati.bsky.social optimize a tech-enabled tutoring program, boosting efficiency & finding low-cost ways to double learning impact. 📄 bit.ly/49MbmC8

What are academic incentives and how do they relate to policy and practice? Can incentives be aligned? Check out today's article to learn about the different incentives in academia vs policy ⤵️

'Academic incentives' are often raised as a reason for research not impacting policy - but what actually are they? Academia remains a black box for most - academics just know how stuff works, and rarely write it down. So we asked @noamangrist.bsky.social for his thoughts ⤵️

An amazing opportunity, I recently used them in a presentation as the example of evidence->practice cycle that all orgs in the field should aspire to

Getting implementation right: 12 experiments to refine tutoring at scale www.wwhge.org/wp-content/u... Evidence from Botswana by @noamangrist.bsky.social, Cullen, & Magat

Tutoring school children is effective, but hard to scale. Researchers @noamangrist.bsky.social, @ccullen.bsky.social, & @janicalapati.bsky.social used a novel A/B testing approach to enhance cost-effectiveness and scalability of a program in Botswana. 🔗 Read the new paper: https://bit.ly/3WYniJn

How can education outcomes be improved under new fiscal pressures? Alongside the 2025 #UKFIETConf in Oxford, @wwhglobaled.bsky.social brought together experts from our Community of Practice, working across the global education sector to share their reflections. www.wwhge.org/resources/sc...

Can A/B testing translate from the tech sector to the social sector? Our new working paper on 12 iterative experiments says “yes” ✅ 58% of our 12 A/B tests improved efficiency. That’s higher than tech benchmarks. 👉New working paper www.wwhge.org/resources/ch...

🚨So happy this is out in the world! Our paper on 12 A/B tests finds that quick, iterative experimentation produced large cost-effectiveness gains in an education program. Encouraging evidence for faster, rigorous learning in the social sector. ‪@noamangrist.bsky.social's summary🧵👇

We ran 12 A/B tests in 3 years. Each built on the last. Iteration = real results: lower costs, higher learning. A nimble way to scale evidence-based programs. 👉New working paper: www.wwhge.org/resources/ch...

🆕 New working paper out now! Cheaper (and more effective) by the dozen: Evidence from 12 randomised A/B tests optimising tutoring for scale, by @noamangrist.bsky.social, @ccullen.bsky.social & @janicalapati.bsky.social. @youthimpactorg.bsky.social 📍 Read more: www.wwhge.org/resources/ch...

📣 Our paper is out on 12 A/B tests all together showing *big* efficiency gains! So excited about this paper & broader approach.

In the latest @wwhglobaled.bsky.social article by the CSAE's @noamangrist.bsky.social, @gamblingondev.bsky.social & co-authors, researchers argue that foreign aid has a continued & critical role to play & highlight specific & highly leveraged roles for foreign aid.

💡NEW: It's time for foreign aid to prioritise foundational learning, argues @wwhglobaled.bsky.social. Their analysis shows that investing in just one year of foundational learning programmes boosts children's future earnings by $164 billion.👇 www.bsg.ox.ac.uk/news/experts...
