Also, keep an eye out for a follow-up project with Eric Edmonds, Martina Jakob, and Carla Coccia (in partnership with @poverty-action.bsky.social), testing mentoring and information to prevent dropout in Guatemala.
Preventing School Dropout at Scale: Experimental Evidence from Guatemala | Journal of Labor Economics: Vol 0, No ja

To sum up: a gov’t-led, ultra low-cost program (USD 2–3/student) reduced dropout at the critical 6th→7th grade transition by 1.2pp (~3%). Effects faded after 2 yrs, highlighting both the promise of these types of intervention to prevent dropout & the need for follow-up support.

marome1.bsky.social
Indeed, in 2019, the Ministry rolled out the guide nationwide; cohort differences vanished thereafter, consistent with this.

marome1.bsky.social
Despite fadeout, ENTRE is very cost-effective: ~0.64 years of schooling gained per USD 100, far above CCTs/scholarships (0.01–0.17). It has a ~27% IRR and a cost–benefit ratio of 7–17. At <$3/student, ENTRE is affordable within the national education budget.

marome1.bsky.social
ENTRE was designed for scale: led by Guatemala’s Ministry of Education using existing staff, costing only USD 2–3 per student. This gov’t ownership reduced the risk of ‘fade out’ often seen when NGO pilots expand.
(See "experiment at scale" by @karthik-econ.bsky.social Paul Niehaus)

marome1.bsky.social
Qualitative data revealed 3 takeaways: (1) ENTRE signaled dropout prevention as a gov’t priority, motivating teachers; (2) the guide gave concrete tools & legitimacy to act; (3) deep barriers (e.g., poverty, social norms, scarce scholarships) remained, limiting long-run impact.

marome1.bsky.social
Admin data let us see longer-term: ENTRE boosted 6th→7th grade transition in 2019, but by 2020–22 gains vanished. Many later dropped out, likely due to a lack of follow-up support in secondary (and other structural factors)

marome1.bsky.social
We use admin data to track student enrollment for several years. What do we find? Dropout decreases by ~1.2 pp from a 34% base (≈−3.3%). Effects similar across arms; lists and nudges add ~0 beyond training+guide.

marome1.bsky.social
These 4,000 schools were randomly split:
• 1,000 got training + guide
• 1,000 got training + guide + risk list
• 1,000 got training + guide + risk list + nudges
• 1,000 were controls.
Schools were spread nationwide, making this one of the largest dropout-prevention RCTs.

marome1.bsky.social
We evaluated ENTRE in 4,000 Guatemalan schools (from 6,080 eligible, ~44% of all 6th graders). Eligibility required enough secondary school supply, excluded the smallest primaries, and only included schools with some predicted at-risk students.

marome1.bsky.social
Finally, some principals received 5 monthly nudges (via the ministry’s portal) to keep dropout top of mind.

marome1.bsky.social
Some schools also received a list of 6th-graders at highest risk of dropping out, predicted using sex, age, GPA, grade repetition & school history. The model identified 82% of future dropouts (See doi.org/10.1080/0964... for more details on the predictive model)

marome1.bsky.social
The core of ENTRE is a half-day training + a practical guide for principals & 6th-grade teachers. The guide offered simple, low-cost strategies: motivate students, help with scholarship information, provide remedial support, engage families, and ease enrollment logistics.

marome1.bsky.social
In 2017, Guatemala’s gov’t & World Bank launched ENTRE, a low-cost early warning system to cut dropout in the 6th→7th transition. It trains principals/teachers, flags at-risk students, and uses behavioral nudges to address knowledge gaps, data deficiencies, and prioritization issues

marome1.bsky.social
Guatemala’s dropout crisis is rooted in deep structural problems: >50% live in poverty, 6th globally in malnutrition, and secondary schools are scarce & urban-biased. While fixing these takes time, we test a low-cost, scalable intervention to reduce dropout now.

marome1.bsky.social
For context: Globally, primary enrollment is near universal, but secondary is not; many drop out in the transition. In Guatemala, 1 in 3 students leave school, moving from 6th→7th grade. Because most schools offer only primary or secondary, switching schools raises dropout risk.

Officially forthcoming at @jlaborecon.bsky.social, our new paper with Melissa Adelman, Francisco Haimovich, and Emmanuel Vazquez on the results from a large experiment with 4,000 schools on how to reduce dropout between primary and secondary schools in Guatemala. Short 🧵below #EconSky

Note that our colleagues in the Business School are also hiring. It’s a fantastic, young department pushing frontier research with strong links to the Econ Department. Great people+ great energy: econjobmarket.org/positions/11...

I have such data for mexico... Not sure if you want it for the US or just generally speaking

marome1.bsky.social
We (Econ at ITAM) are hiring:econjobmarket.org/positions/11841
Pay is competitive with the US (in absolute terms), working language is English, virtually no service work, spend ~80% of your time in research, and you get to live in one of the coolest cities in the world.

This is part of a larger agenda studying ECE in India.Expect more soon 🙂

+check out @petterberg.bsky.social, he is on the market and is fantastic;he was the driving force behind this paper: sites.google.com/view/petterb...

His JMP focuses on the long-run effects of outsourced schools in Sweden.

Our themes relate to other great work:

RCTs: See work by Ganimian @karthik-econ.bsky.social and Walters on improving AWCs; by @joshtdean.bsky.social @seema.bsky.social on vouchers for private preschool

Facts: See ASER Centre Early Years and main ASER Reports

marome1.bsky.social
Our results provide a unified view of public vs private effects from preschool to the end of primary edu (+ links to inequality).

Substantively, it supports the recent focus on improving ECE systems in India.

New: understanding edu *markets* at this stage is important.

marome1.bsky.social
Villages with better public pre/primary schools also have better private sectors ➡️ unequal access to quality education across villages.

Why?

Maybe public sector quality induces better performance from the private sector (as Tahir, Bau,Das @nkarachiwalla.bsky.social and Khwaja find in Pakistan)?

marome1.bsky.social
Result 3: Private preschools outperform public ones in nearly ALL villages.

In primary schooling, this is more variable across geographies.

(Doing this correctly needs Bayesian shrinkage; details in paper)

marome1.bsky.social
Result 2: Richer kids are far more likely to attend private schools (+35pp in preschool, +39pp in primary). This explains ~60% of the SES test score gap at preschool ages (but none in primary, since private schools show no value-added there).

marome1.bsky.social
Result 1: Average value-added in private preschools larger than public AWCs by 0.74σ in math & 0.59σ in Tamil.

By contrast, private primary schools have NO positive value-added over government schools in these subjects (we did not test English)

marome1.bsky.social
Sample: Household-based panel data on ~19k students (age 3-10) across 215 villages. All children tested one-to-one. Age-appropriate tests linked on a common scale using IRT (using overlaps across ages). Items align with national goals for foundational skills.

marome1.bsky.social
Context: Tamil Nadu, nearly all kids 4-5y enroll in *some* preschool

Public: Mostly anganwadi centres. Free to attend, only 1 worker + 1 helper. In TN, ~38 mins/day on cognitive tasks.

Private: Nursery/KG, often linked to primary sch. Fee-charging, focus on early learning.

Early Childhood Education is central to India’s NEP and global edu goals. Our(@petterberg.bsky.social @singhabhi.bsky.social) new paper at EJ (@resmedia.bsky.social ky.social, bit.ly/4gOtoVV), shows private ECE outperform public options, explaining 60% of the SES gap. In primary, NO private premium.
