📣 Join us for practical how-tos on A/B testing on March 11 w/ @wwhglobaled.bsky.social @youthimpactorg.bsky.social @poverty-action.bsky.social Gates Foundation The Agency Fund and the South Africa Department of Basic Education: www.wwhge.org/events/itera...
💡 How can large-scale government and World Bank programmes be improved in real-time? A partnership between the World Bank and @wwhglobaled.bsky.social used A/B testing to keep implementation on track in the context of a large-scale TaRL programme in Ghana.

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. 🧵

📣 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:

“Teaching to the individual level of the child is more effective than teaching a one-size-fits-all curriculum.”

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.

👇 We've distilled a decade of lessons on A/B testing in the social sector in a new toolkit hot off the press to enable others to do the same. Check it out and keen to hear feedback -- we always continue to iterate & improve! Thanks to so many who enabled this learning culture & tangible techniques.
✨A stimulating panel on the science of scale at the Australasian AID Conference. An honor to share reflections alongside movers & shakers in government in Australia, the Philippines, and PNG.

📢 #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.

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
📣 @youthimpactorg.bsky.social is hiring a Learning Partnerships Lead, who will lead A/B testing partnerships & high-profile research-to-action partnerships: www.youth-impact.org/join-our-tea...
➡️ An exciting role for those who care about rigorous evidence being used in practice on a day-to-day basis
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.

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.

+ many more who are supporting this type of iterative learning across broader array of programs & sectors.
Huge shout out to implementers, donors, research, & thought partners who have helped us work on this set of 12 tests: @youthimpactorg.bsky.social @wwhglobaled.bsky.social, Mulago, Agency Fund, FCDO, Marshall, UBS, @jacobsfoundation.bsky.social, @blavatnikschool.bsky.social, @oxfordcsae.bsky.social
We measure practitioner teacher beliefs and show they update accurately towards identifying "what works," revealing the power of embedded learning to drive change on the front lines
