NCER Member briefing on the strict limitations regarding the use of the 2019 NCER CLA Analyses (DfE)
The strict limitations set out below are in place for the use of the 2019 NCER CLA Analyses (DfE). The limitations will remain in place until the DfE CLA Outcomes statistical publication has been published in March 2020.
If required it is possible for local authorities to use the 2019 NCER CLA Analyses (DfE) with Ofsted before the DfE CLA Outcomes statistical publication is released. This use of NCER CLA Analyses (DfE) has been approved by the DfE.
The limitations outlined below do not apply to NCER CLA Analyses (LA) where SSDA903 data has been loaded into Nexus by local authorities.
NCER are pleased to report that the DfE have now released the full 2019 CLA data to NCER which we match to the latest attainment data in Nexus. NCER CLA Analyses (DfE) in Nexus will include national aggregated data, subject to certain limitations being required by the DfE. Local authorities must read and comply with these limitations for the use of the 2019 NCER CLA Analyses (DfE) which are outlined below.
The DfE have imposed strict usage limitations for the 2019 NCER CLA Analyses (DfE) in Nexus. These limitations are imposed on all local authorities due to the early visibility of aggregated national data (ahead of the DfE CLA outcomes statistical publication in March 2020).
NCER specify that all 150 local authorities who are part of the NCER CLA data project must read and comply with these restrictions. Failure to do this may result in the DfE withdrawing access to the 2019 DfE data and data in future years.
Strict DfE Limitations of NCER CLA Analyses (DfE) usage
To have access to the 2019 CLA data, and allow the NEXUS reporting system to produce early aggregated national data, the DfE required NCER to confirm that we have imposed strict limitations relating to the use of the early aggregated data on all NCER member authorities. On behalf of member authorities NCER has given this confirmation.
NCER requires that all 150 local authorities who are part of the NCER CLA data project read and ensure compliance with the following restrictions. Failure to do this may result in the DfE withdrawing our ability to have access to the 2019 data and may have an impact on NCER’s application for access to the finalised 2020 data.
The DfE states that there should be absolutely no intention to use the data in any way that might seem to duplicate the data prior to the publication of the national data by the DfE in March 2020.
The DfE have advised that “any published CLA or CLA matched with NPD figures at a local level must be based on no lower than 6 cases or else suppressed (e.g. replaced with an c, with a note “c in this table means the figures have been suppressed due to small numbers”). National and regional figures should be rounded to the nearest. Percentages less than 0.5 % should not be shown (e.g. replaced with “-“with a note to say the % is negligible). Percentages should be rounded to whole numbers but where the numerator is five or fewer or the denominator was 10 or fewer, they should be suppressed and replaced by a cross (c).
For CLA data zero is allowed. For CLA matched with NPD data, zero is not allowed.
Even if only one cell requires cell suppression, then NCER system must suppress at least one other component cell (the next smallest) to avoid calculation of suppressed values from the totals. In this case the next smallest number less than 20 should also be suppressed.”
We can confirm that the above requirements are being adhered to in Nexus.
The DfE has also stressed that NCER and its member authorities shall not reproduce the data or include secondary analysis of the data within any publication without the prior written consent of the Data Controller (DfE) unless such reproduction / publication is included within the Permitted Use.
Consent is only valid if given in writing, in advance of reproduction or publication of the data. You must present your research and/or analysis at least 48 hours prior to any publication being released to firstname.lastname@example.org
As the CLA data has not been checked by schools, it should only be used by those with a legitimate need to use it for managerial, operational or other appropriate decision-making purposes at an early stage.
In addition, it should NOT be used for-
- Issuing public statements based on the information before the official statistics are published in March 2020
- Supporting direct action on schools or dictating school funding
- Publication or public pronouncement of any analyses at aggregate or school level without permission from the DfE
A further note from NCER;
We do not believe that any local authority will misuse the CLA data in any way that would undermine our agreement with DfE.
By accepting these limitations there should not be any impact on the operational use of the NCER CLA Analyses (DfE).
