1. Internal review by UK LLC#

Review by the UK LLC Application Review Panel assesses applications against the Five Safes Framework and checks that all requested fields are filled out appropriately and fully. In particular, applications are reviewed to ensure that the data being requested are available, can be used for the proposed research (i.e. align with data owners’ terms of use) and are relevant to the research question. Applicants must justify the inclusion of data of ‘elevated sensitivity’ such as socially sensitive data (e.g. mental and sexual health data) and demographically sensitive data (e.g. ethnicity). The panel ensures that public good has been addressed, that public involvement plans are included and that a lay summary has been provided. The panel also assesses whether ethical requirements have been met following the UK LLC ethics decision-making tree - see the Complete your application guide for further details.

Any questions or concerns are sent back to the applicant(s) and resubmitted applications are re-reviewed by the UK LLC Application Review Panel. Once the UK LLC panel is satisfied that the application can proceed it will be sent out for external review. Applications that are declined may go through the appeal process once. Applicants must address all comments, questions and criticisms fully for the appeal to be considered.

2. External review by the public and data owners#

Applications are reviewed by:

1. The individual Longitudinal Population Study (LPS) Data Access Committees – each LPS Data Access Committee is responsible for reviewing the application against their LPS-specific application review framework. UK LLC collates and records the LPS’ responses and shares this information, plus any stated conditions, with the applicant.

2. The UK LLC Data Access Public Review Panel – this panel focuses on the lay summary and public involvement plans within each application and assesses the overall public good. Applicants may be asked to present their research question(s) to the panel at an online meeting (see meeting dates in Table 1). If you want to aim to be considered at the next panel meeting (if required), please submit your application at least four weeks in advance. Note, all meetings run 12.30-1330h and if required to attend, your presentation followed by questions from the panel will last approximately 15 minutes in total.

3. The UK LLC Linked Data Review Panel – this panel focuses on reviewing the application against the linked data owners’ requirements. It takes on board the comments of the UK LLC Data Access Public Review Panel. As you can see in Table 1, this panel usually meets approximately one week after the public review panel.

4. Once non-health administrative data becomes available, applications requesting that data will be sent to relevant data owners and UK Statistics Authority’s Research Accreditation Panel (UKSA RAP).
