Privacy notice - September 2020

In line with the EU General Data Protection Regulation (GDPR), there are certain things that we want to let you know about how information will be processed in the evaluation of Hanen LLLI. In this privacy notice, we explain the legal basis for data processing, who will have access to participants’ personal data, how data will be used, stored and deleted, and who you can contact with a query or a complaint.

Who’s who?

This evaluation is being carried out by independent evaluators, the National Centre for Social Research (NatCen), commissioned by the Education Endowment Foundation (EEF).

Who will access personal data?

NatCen are carrying out this evaluation and will have access to nursery and practitioner information, evaluation interview recordings and transcripts of interviews with nursery staff and program leaders, survey responses, children’s assessment and attainment data and sample files including staff contact details and children’s names, dates of birth and unique pupil numbers (UPNs). All assessment and attainment data and interview responses will be anonymised before being analysed.

McGowan Transcriptions ( is the transcription service we use to transcribe our interview data. They will have access to recordings and transcriptions from all interviews. McGowan Transcriptions is on our approved supplier list and compliant with all our information security policies.

Qualified speech and language therapists and Early Years consultants will visit nurseries to conduct assessments with children. They will have access to pupil names, dates of birth and pupil assessment scores only for the nurseries where they will conduct assessments.

How will the data be used?

The data collected will be used for research purposes only.

Assessment data from the vocabulary assessments, and attainment data from the National Pupil Database (NPD) will be used to inform our impact evaluation. All assessment data will be anonymised before being analysed.

Information and opinions gathered from interviews and surveys with practitioners and managers will be used to inform our process evaluation. All interview responses will be anonymised before being analysed.

All data will be treated with the strictest confidence – no nursery, staff or children will be identified in any report arising from the research.

NatCen will share data from the impact evaluation (including information from the NPD) with the Department for Education, the EEF’s archive manager and with the Office for National Statistics and potentially other research teams. Further matching to NPD and other administrative data may take place during later research.

NatCen will securely delete personal information about participants no more than six months after the evaluation is finished (by June 2023 at the latest).

The legal basis for processing data

For this evaluation, NatCen is a data controller who also processes data. This means that we are responsible for deciding the purpose and legal basis for processing data. The legal basis is “legitimate interest”. This means that we believe that there is a genuine reason for us to process this data (to evaluate the impact of Hanen LLLI), that this data is needed to fulfil this purpose (we couldn’t evaluate Hanen LLLI without this information), and that using this data won’t interfere with individuals’ interests, rights or freedoms.

Who can I contact with a query or a complaint?

You have the right to raise any concerns with the Information Commissioner’s Office (ICO) via their website at

You also have the right to object to your child’s information being used in this evaluation. If you object, please let us know by getting in touch at or by calling 0207 549 7158.
