AlphaPlus is delighted to announce that we are working with the Organisation for Economic Co-operation and Development (OECD) to deliver the International Early Learning Child Well-being Study in England on behalf of the Department for Education.

What is IELS?
The International Early Learning Child Well-being Study is an international survey that collects detailed information on key competencies of children across eight countries. It aims to help countries to improve children’s early learning experiences in order to better support their development and overall well-being.
Research into how children develop at this early stage has been limited and before the study’s introduction, it was difficult for nations to easily compare evidence and share best practice. Data from this survey will be used to help countries to better support children’s early development and improve their long-term well-being by identifying key factors that drive or hinder the development of early learning.
AlphaPlus will be working with OECD to deliver the study in England. Our role involves:
- Contributing to the design and development of the study
- Selecting the random sample of pupils to take part in the trial and the main study
- Recruiting and training test administrators to deliver the assessment to pupils
- Managing the administration of surveys to parents/caregivers and to teachers
- Analysing the data from the assessments and surveys
- Reporting on the findings to DfE and disseminating these to policy officials and external stakeholders

How will data be collected?
Data will be collected in two key ways:
- Direct assessment of pupils on tablets by a trained test administrator. These assessments take 15 minutes and will each cover one of four topics: emergent literacy, emergent numeracy, executive function, and empathy.
- Indirect assessment through written and online questionnaires to be taken by parents/caregivers, teachers and the test administrators.
Who will take part?
3,000 pupils in 200 schools will be randomly selected to take part in the main study. Parents will be notified that their children have been selected in Autumn 2023 for the field trial and Autumn 2024 for the main study.
Can I opt out?
Yes. We will obtain parental consent at project outset, and parents will have the opportunity to withdraw from the project at any stage.
How will you ensure pupil wellbeing is prioritised?
Child well-being is of the utmost importance in this study and has been considered at every stage:
- The assessment material will be delivered by trained administrators, in one-to-one situations, in a familiar and controlled environment of the child’s centre or school
- All assessment materials have been extensively trialled to be appropriate for children of this age. Pupils do not feel like they are taking a test but instead engaging with fun and age-appropriate stories and games.
- Children are asked at every stage whether they have enjoyed the activities. Feedback from children in the Study has been overwhelmingly positive, on both the stories and games and on the touch screen functionality of the tablets.
- Children are able to stop the assessment or withdraw entirely from the study at any time.
How secure will participants’ data be?
We take the privacy of all participants in this survey very seriously, and we have robust data protection and security processes in place. All data will be processed in line with the Data Protection Act and General Data Protection Regulation and no individual child, parent, carer or teacher will be identified or identifiable in any reporting.

England is taking part in The Organisation for Economic Co-operation and Development’s (OECD) International Early Learning and Child Well-being Study (IELS).
The purpose of the study is to produce statistics on children’s learning and development, in order to learn more about how best to support children in their early years. The Department for Education (DfE) has commissioned AlphaPlus to carry out the study in England in 2024 and 2025.
We take privacy and confidentiality very seriously and adhere strictly to the Data Protection Act and General Data Protection Regulation (GDPR). To ensure confidentiality, no information concerning individual pupils, parents/carers, teachers or schools will be identified or identifiable in any reporting. This privacy notice tells you what DfE, and its approved contractors, will do with the information we collect from parents, children and teachers as part of the IELS study and how we will ensure privacy of personal information. It explains:
- information to be collected for the study
- organisations that information will be shared with
- how we will use the personal data
- what makes it lawful to collect and share the information
- how participation affects you
- security and confidentiality
- contact details and further information
Participation in the study is voluntary. If there are any questions you do not wish to answer you may leave them blank. By providing information as part of this study, you are agreeing to the use of the information you provide as set out in this privacy notice.
Information to be collected for the study
The study will collect information about children’s development and their characteristics from their parent(s) or carer(s), their teachers and by studying the children themselves. No individual child, parent or teacher will be identified or identifiable in any reporting.
The DfE’s approved contractors for this study (AlphaPlus) will collect the following personal information about participating children from participating schools in order to administer the study:
- Date of birth
Special category data such as:
- Information on special educational needs.
We also ask teachers for their assessments of each participating child’s cognitive and social/ emotional development.
their own characteristics:
- level of education
- relationship to child
- family composition
- English as an additional language
- whether born in England
- current employment
- their child’s characteristics:
- skills and abilities
- physical health
- special educational needs or disabilities
- cognitive and social/emotional development
- English as an additional language
- whether born in England.
Information that we collect from teachers will be their:
- employment status
- how long they have been in post
Organisations that information will be shared with
AlphaPlus will collect this personal and special category data on behalf of DfE but will remove all information that could identify individual children, teachers or parents before this information is shared with The Organisation for Economic Co-operation and Development (OECD). This means that OECD will receive an anonymised set of data for its production of aggregated statistics.
How we will use the personal data
For the purposes of this research, the DfE and its approved contractors will link the information to other information DfE already holds (such as on the National Pupil Database) or that it is lawfully permitted to access from other sources. This is to avoid repeatedly asking participants to give us information that we already hold and to enable analysis of the longer-term benefits of early learning.
DfE (or its appointed contractors) will keep the personal information indefinitely with appropriate safeguards in place to protect the information for the purposes of research and statistics (as permitted under Article 19 (1)(b) of the Data Protection Act 2018 and Article 9 (1)(j) GDPR), as the benefits of early learning are known to be related to life outcomes in adulthood and analysing the information from this study would enable greater understanding of this effect. Neither DfE (or its appointed contractors) will share any information that would identify individual participants in the study or other individuals to whom they refer, with any third parties unless required to do so by law.
What makes it lawful to collect and share the information?
Personal data will be collected by DfE’s appointed contractor on DfE’s behalf for the purposes of research and statistical analysis that is in the public interest pursuant to Regulation 3(6) of the Education (Individual Pupil Information) (Prescribed Persons)(England) Regulations 2009. The legal basis for processing this data is Article 6(1)(e) of the General Data Protection Regulation where “processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the [data] controller”.
The processing of sensitive personal data, consisting of information as to racial or ethnic origin, this is necessary for the purpose of identifying or keeping under review the existence or absence of equality of opportunity or treatment between persons of different racial or ethnic origins as permitted under Article 9 (1)(j) of the GDPR. This is with a view to enabling such equality to be promoted or maintained and is carried out with appropriate safeguards for the rights and freedoms of data subjects.
How participation affects you
No individual child, parent, or teacher will be identified or identifiable in any reporting. Participation (or non-participation) in this study will have no influence on parents, teachers or children. Parents/carers are free to change their mind at any time and withdraw, or withdraw their child/children, from the study.
Parents: if you agree to provide your contact details, DfE’s contracted partner will gather this information and pass it to the DfE. The DfE then might pass this information to another contractor to ask you to take part in further research. Please note that, if contacted, you will be under no obligation to take part and you can change your mind at any time. If you agree to participate, you will not be identified or identifiable in any results.
Security and confidentiality
Any personal data collected by DfE (and organisations acting on its behalf) will be handled securely and confidentially. It will only be used for the purposes of research and statistical analysis relating to children’s early learning and development and related topics.
