Methods	Study design: cluster‐RCT design
Participants	School type: government, independent and Catholic primary schools Region: NSW, Australia
Interventions	Number of experimental conditions: 2 intervention and control Policies, practices or programmes targeted by the intervention The intervention seeks to encourage the purchase of healthier foods and drinks for school canteen lunch orders, that is, items lower in energy, saturated fat, sugar, sodium or a combination of these consistent with the NSW Healthy School Canteen Strategy. Implementation strategies EPOC: monitoring the performance of the delivery of healthcare ‐ The canteen manager at each intervention school will receive a tailored feedback report summarising the results of an assessment of their online canteen menu against the 'NSW Healthy School Canteen Strategy: Food and Drink Criteria', conducted by a trained dietitian.
Outcomes	Outcome relating to the implementation of childcare service policies, practices or programme At baseline and follow‐up, an experienced dietitian will use the assessment of nutrition quality (above) to calculate the proportion of 'Everyday' items, 'Occasional' items and 'Should Not Be Sold' items within each menu, to compare against the 'NSW Healthy School Canteen Strategy: Food and Drink Criteria' which state that ≥ 75% of the menu should be 'Everyday' items and ≤ 25% should be 'Occasional' items. The proportion of schools meeting the criteria at baseline and follow‐up will be reported per group to determine if changes to the availability of healthier items were made.
