Plain English Summary
Background
National School Food Standards were introduced in 2006 and are a legal requirement for most state schools. In 2013, the School Food Plan, a wider set of voluntary recommendations for schools, was developed, and subsequently updated standards were introduced in 2015. There is little information on the impact of School Food Standards on school food provision and pupil food intake in secondary schools, and the impact of the updated standards and the School Food Plan recommendations has not been explored. The way in which the School Food Standards legislation was introduced means that all academies and free schools set up between 2010 and 2014 are not legally obliged to meet the standards. This gives an opportunity to examine the influence of a legal requirement to meet the standards by comparing schools which are required by law to meet them with those that are not. Specifically, we want to assess whether the standards influence pupils' sugar intake, as adolescents have high levels of sugar consumption, which can lead to obesity and poor dental health.
Aims
We will make comparisons between secondary schools required to meet the standards and those that are not required to meet the standards. We will compare: the food provided and sold in schools; the school food environment and culture; the healthy eating and cooking skills curriculum; the cost to schools of measures to improve healthy eating and food provision; the consumption of foods high in sugar, other elements of the diet and dental health in pupils. We will also explore the extent to which schools vary in how the School Food Standards and School Food Plan are implemented.
Who can participate?
Secondary schools in the West Midlands and pupils from years 7, 9 and 10 in those schools.
What does the study involve?
We will examine whether a requirement to adhere to the standards policy is associated with the provision, sale and consumption of healthier foods (focusing on sugar intake) in schools, and whether and how requirement to adhere relates to how well the School Food Plan is implemented. This will be done through collation of data from a variety of school documents (including relevant school policies, food and catering contracts, relevant curricular teaching), researcher observations (to assess the school environment and culture including the food on offer and the eating spaces in schools) and questionnaires to key staff members, governors and parents to gain their views and experiences of the food standards, the school eating environment, culture and curriculum. We will ask pupils from years 7, 9 and 10, in school time, to complete an online survey including a 24-hour dietary recall tool, and questions about the food they eat and the health of their teeth. We will compare the average sugar intake, tooth decay symptoms and treatment, and intake of other food types among pupils in the two school groups. We will compare information on school food sales across the two school groups. We will use the above information to identify 4-8 schools with varying levels of provision and sale of healthy foods, in which we will collect more in-depth information through interviews with key staff members and small discussion groups with pupils. We will explore whether consumption of sugar and other foods is influenced by how well the School Food Standards and School Food Plan are implemented.
What are the possible benefits and risks of participating?
The results will help us to assess the impact of the national School Food Standards. This information will be used to inform the Department for Education and Department of Health to enable further development of national policy relating to school food. In turn, this may help to shape the health of future secondary school pupils. Additionally, pupil and parent participants will be given a £5 shopping voucher as a thank you for their time spent participating in our study.
Schools will be provided with a summary of the data collected from their school, which may support any internal evaluation of school food. The process of collecting the views of pupils, parents, staff and Governors will also provide an additional method for the school to ensure their voices on school food provision and education are heard. All schools who take part in the study will be given £300 to cover the costs of their involvement.
There are no anticipated risks to those taking part in this study.

Scientific title
An evaluation of the implementation of national school food standards in secondary schools and their impact on the school food environment and pupil intake of free sugars: a mixed methods study
Acronym
FUEL
Study hypothesis
Evidence from dietary surveys indicates that dietary intake of free sugars and sugar sweetened beverages (SSBs) among UK children and adolescents regularly exceeds recommended levels. These high intake patterns are of public health concern given the association between sugar consumption and obesity. Patterns of school food consumption are an important determinant of total dietary profile, with up to a third of children’s energy and micronutrient intake provided by lunch on school days. Adolescence is a key period for the establishment of dietary patterns, and in school adolescents have more choice and greater autonomy regarding the food they eat compared with younger children. Therefore a healthy school food environment may have a significant influence on the dietary intake of adolescents.
National School Food Standards (SFS) have been in place in England since 2006 and were updated in 2015. They are a legal requirement for most state schools. The Standards are a set of requirements for school food to help children develop healthy eating habits and ensure that they get the energy and nutrition they need across the whole school day. In addition to the national SFS, the School Food Plan (SFP) was launched in 2013. This provides a wider set of non-statutory recommendations for schools which aim to address the overall ethos of the school in relation to food, promoting adoption of a ‘whole school’ approach. There has been little evaluation of the impact of the SFS on the diets of pupils in secondary schools, and to date, there has been no evaluation of the implementation of the SFS within secondary schools, or the influence of the wider SFP recommendations on the overall ethos of the schools in relation to food.
The way in which the SFS legislation has been introduced in England means that there are a group of academies and free schools that are exempt from the legal requirement to meet the Standards. This gives an opportunity to examine the influence of the SFS legislation by comparing these exempt schools with those that are mandated to meet the Standards.
We aim to assess whether the mandatory SFS and additional SFP recommendations influence the food provided and sold in secondary schools; the school food environment and ethos; and the healthy eating and cooking skills curriculum. We also aim to assess the impact of the SFS and SFP on sugar and other dietary intake, and the dental health of secondary school pupils. In addition, we will explore the extent to which schools vary in how the SFS and SFP recommendations are implemented; the cost to schools and families of measures to improve healthy eating and food provision; and the economic impact of the SFS and SFP.

Intervention
Current interventions as of 31/12/2019:
This research consists of two stages. In the first stage, a variety of data on SFS and SFP implementation and school and pupil outcomes will be collected at the school and individual pupil level. We will aim to recruit an equal number of schools mandated and not mandated to comply with the SFS, with pupil recruitment occurring from one selected class (form groups or class groupings where there is no streaming and all pupils have to attend) from each of three different year groups for every school. We will compare outcomes at the school level (food provision and sales, school meal uptake, eating environment, food curriculum, school food culture, and costs related to these factors) and at the individual level (sugar and other dietary intake, dental caries experience) in the two school groups. We will also capture data to explore the implementation and embedding of the SFS, SFP and the influence of the school context on this. We aim to develop a typology of schools relating to school food: provision; environment; culture; curriculum, and the wider school context, which will reflect the degree of implementation of the SFS, SFP and other local initiatives to improve the diets of pupils. In the second stage, a smaller number of case study schools (4-8) will be identified for in-depth qualitative evaluation with school staff (interviews) and pupils (focus groups). Schools will be sampled to ensure inclusion of a range of schools in terms of level of SFS/SFP implementation and institutional characteristics such as school size.
Data will be collected through the following methods/tools:
• Key information survey to head teachers
• Costings survey for completion by senior management
• Survey to key staff and Governors identified by the school to have roles relating to food provision, eating environment, food curriculum, or SFS/SFP implementation (including head teachers, lead catering staff, PHSE leads, teachers with responsibility for the food/cooking curriculum, relevant representatives from the governing body)
• Pupil survey, including a Paediatric Quality of Life measure (CHU-9D) and dental health measures
• Pupil 24 hour recall dietary assessment tool
• Parent survey to parents of pupils participating in the study
• Observation checklist for auditing the school food environment and ethos (food outlets; dining and communal facilities; food consumption behaviours; wider environment within and surrounding the school)
• School food compliance checklist for auditing school food provision (using menus, price lists and observation)
• Canteen sales data (aggregated data on food sales for two (non-continuous) months in the academic year)
• Analysis of key documents from schools e.g. policies; minutes of Governors meetings; catering contract; menus
• Collection of key data from schools e.g. school meal take-up
Data collection tools to measure compliance with the SFS are based on the national SFS checklists for school lunches and school food other than lunch.
Data collection tools to measure implementation of the SFP are based on the national School Food Plan checklist for head teachers, guidance for Governors and the creating a culture and ethos of healthy eating document aimed at school Senior Leadership Teams.
Normalization Process Theory has underpinned the design of staff survey questions relating to the implementation and sustained embedding of the SFS and SFP recommendations

Findings will be of value at: national level (to inform government school food policy); school level (to enable effective implementation); the public (to support wider understanding of school food policy).
We will produce the following outputs:
1. An updated online dietary assessment tool (Intake24), adapted for use in a culturally diverse population. This will be of future use in nutritional epidemiological or intervention studies in culturally diverse communities.
2. Full study report published in the National Institute for Health Research Journals Library (https://www.journalslibrary.nihr.ac.uk/#/)
3. Open access publications and conference presentations on:
a. The implementation of the school food standards and school food plan in secondary educational settings, including the variation in practice and the barriers and facilitators to implementing such policy
b. The costs associated with implementing school food standards and related policy in secondary educational settings
c. The impact of statutory school food standards on pupils’ dietary intake and dental health
d. The association between the level of implementation and embedding of school food standards and wider school food policy/initiatives, and pupils’ dietary intake and dental health
We will present findings at national and international conferences, and targeted journals will include both general medical journals and specialist journals
4. A short brief for policy audiences.
We will disseminate findings to key national agencies (Department of Health, Department for Education, Public Health England, School Food Alliance, National Association for Headteachers etc.), and to local level organisations (Regional School Commissioners, Local Governors’ Association etc.)
The information gained from the study will also be disseminated at a local level through Local Authorities.
In addition to preparing reports for different agencies, we will engage in the following dissemination activities:
• Communicating study findings through the educational and general press;
• Presenting at meetings held by key networks and organisations
• Producing a summary report for participating schools, pupils and parents, and for the non-participating schools who have expressed an interest
