In Simple Words
When a government sends a predictable, automatic check to every school based on a published rule, families know it is coming and cut back their own contribution. But when funding comes from an irregular, unpredictable pool awarded at random times, families cannot plan around it, so the money actually adds new resources to the classroom.
Pupils in surveyed Zambian schools
- No discretionary grant
- Comparison schools
- Received discretionary grant
- English score gains were 0.103 SD higher
Annual gains in observed Zambian schools, 2001–2002. SD measures score differences; unmeasured school differences could explain part of the association.

Public education funds distributed via simple, predictable rules are easily anticipated by households, allowing them to offset private expenditures. Discretionary funding streams create uncertainty that prevents preemptive private crowding out.
Participants
172 primary schools in 4 provinces of Zambia (~3,440 grade 5 students tested across 2001-2002).
Study Design
Cross-sectional panel regression comparing predictable rule-based BESSIP grants ($600–$650/school) against unpredictable district discretionary transfers.
Results
Predictable rule-based grants had no correlation with test score gains (-0.024 SD in English, -0.010 SD in math), whereas receiving unpredictable discretionary grants (median ~$3/student) significantly increased test scores by 0.103 SD in English (p < 0.05) and 0.096 SD in math (p < 0.10).
Takeaway
Distribute public educational grants through flexible or discretionary allocation channels when the policy goal is to generate immediate net gains in student learning.

- Median
The middle number after arranging the values from smallest to largest. If there are two middle numbers, use their average.
ExampleFor the values 2, 4 and 12, the middle value is 4. The median is 4.
