A School Canteen Policy That Has to Show Results in One Year
You sit on a joint MOH-Ministry of Education committee for one governorate. There are 40 intermediate schools (students aged 11-14), about 18,000 students in total. A baseline survey found that 62% of students buy food from the school canteen at least four days a week; the top sellers are chocolate croissants, crisps, sweetened fruit juice and karak tea. Only 8% reported eating vegetables at school. Using WHO growth reference cut-offs, 28% of students measured above the 85th centile for BMI-for-age, and 34% said they ate no breakfast on school days. Canteens are operated by private contractors on three-year contracts with the Ministry. The school day starts at 07:15 and the only break is at 09:45, lasting 20 minutes. Your first-year budget is KD 12,000, and the committee wants measurable results within one academic year.
1. Select three interventions for the first year and justify each on mechanism and feasibility. State what you would deliberately not do, and why.

First, a canteen food standard with a pricing lever: define permitted, limited and prohibited items, and require that at least two of the permitted items are cheaper than the best-selling crisps. Price and availability beat education alone - a 12-year-old with 20 minutes and a small amount of money buys what is in front of them at a price they can afford. Setting the standard also converts an abstract nutrition message into a structural change that does not depend on willpower.
Second, a breakfast window before 07:45. With 34% skipping breakfast and a single break at 09:45, the school has created a five-hour fasting window in growing adolescents. A supervised grab-and-go cart with laban, wholemeal bread with cheese or foul, and fruit addresses the single most tractable behaviour in the data and needs no curriculum time.
Third, a peer-led canteen audit: trained students score their own canteen monthly against a simple checklist and results are posted publicly. This creates local accountability and reduces enforcement burden on staff.
What I would not do: a one-off lecture campaign or a BMI-screening-and-report-card programme. Both consume budget, are known to be weak or harmful (weight reporting without support increases stigma and disordered eating risk), and produce no structural change. With KD 12,000 for 40 schools, everything not tied to food supply or access is unaffordable.
2. The canteens are run by private contractors on existing three-year contracts. How do you secure compliance without a legal fight?
Read the worked answer
Start from what the contract already permits. Most Ministry contracts contain a clause on compliance with Ministry standards and on the nutritional adequacy of food served, and a clause allowing the Ministry to issue operational circulars. The committee's first move is a legal read of the contract to identify that lever, then to issue the food standard as a circular rather than as a new contractual obligation - this avoids reopening pricing.
Second, make compliance commercially rational. Contractors lose money when unsold chocolate croissants are thrown away; they gain when a permitted item sells. Offer a phased timetable (three months' notice, then a pilot in five schools) with a margin protection arrangement: the Ministry agrees not to tender the canteen for a further term with a competitor if the contractor meets the standard, and publishes school-level compliance data that parents can see. Parental demand is the strongest commercial pressure available.
Third, build capability rather than blame. Run two practical workshops for canteen staff on low-cost compliant items using local ingredients - laban, hummus, foul, cheese and cucumber sandwiches, seasonal fruit - with costing sheets in KD per portion. A contractor who is told to stop selling juice but has no replacement product and no costing will fail.
Finally, escalate in a documented sequence: written notice, corrective action plan with dates, joint audit, then formal contract review. Keep the health authority's data on your side of the table.
3. Design the evaluation: what indicators, measured how and when, and what confounders would you pre-specify?
Read the worked answer
Three tiers of indicators. Structural (measured monthly by audit of all 40 canteens): percentage of canteen items meeting the standard, price of the cheapest permitted item versus the cheapest prohibited item, and availability of a breakfast option. Behavioural (measured at baseline, mid-year and end-year using the same anonymous student survey): percentage buying canteen food daily, self-reported breakfast on school days, and a short food-frequency item for vegetables and sugar-sweetened drinks. Outcome: BMI-for-age z-score distribution using WHO reference, collected only through the existing school health screening, reported as population prevalence above the 85th centile, never as individual feedback.
Process measures matter as much as outcomes in a one-year window: number of schools implementing fully, contractor compliance rate, and student participation in the audit.
Pre-specify confounders: season (Ramadan and summer shift eating patterns and survey timing), the five pilot schools being non-random and possibly better-resourced, secular trends in adolescent obesity, and social desirability bias in self-reported diet. Mitigate by using a comparison group of five schools that receive the survey but start the intervention a year later, by standardising survey timing outside Ramadan, and by pre-registering the analysis plan. With 12 months, structural and behavioural change is a realistic target; change in BMI prevalence is not, and the committee should be told that at the outset so that a null obesity result is not read as programme failure.
