Initial teacher training performance profiles

Methodology

Data Collection

The initial teacher training performance profiles are collected each year for trainees in the final year of their ITT training. This year, the DfE has again collected data on the Database of Trainee Teachers and Providers (DTTP). The main collection period occurred from September to November 2020 but in some cases further changes were made directly by the DTTP team in agreement with providers. High level summary tables of trainee numbers for each ITT provider were shared with the relevant provider in January 2021, for checking ahead of data cleaning. The figures shared at this time may differ from those in the final publication due to further data cleaning being carried out after the data had been signed off.

The definition of final year trainees, as well as all other definitions in terms of data collected, remains the same as in ITT performance profiles for academic year 2017/18 (see below), so all comparisons remain valid over time.

For the academic year 2019/20, we received data from all 238 providers. This consisted of 170 SCITTs, and 68 HEIs. All data were reviewed, confirmed and signed-off by a designated person at each provider.

Coverage

The initial teacher training performance profiles covers outcomes for final year initial teacher trainees in England for the academic year 2019/20. 

Confidentiality

The Code of Practice for Official Statistics requires that reasonable steps should be taken to ensure that all published or disseminated statistics produced by the Department for Education protect confidentiality.

To do this small numbers are suppressed for sensitive characteristics and for very small providers.

This suppression approach is consistent with the Department’s statistical policy. Symbols used to identify this approach in published tables are as follows:

Quality assurance 

Data for the ITT performance profiles are completed, reviewed and signed off by a designated person at each ITT provider. The data collection and publication production teams within the Department for Education carry out a number of quality checks on the data throughout the data entry process. After data was extracted on 4th May 2021 (excluding employment data which was extracted at a later date), a quality assurance process was undertaken by the publication production team. This process included detailed quality checks across the dataset. 

This quality assurance process identified a small number of issues. These, along with the solutions that have been implemented, are outlined below.

  • A small number of trainees were identified which were incorrectly recorded as undergraduates when they should have been postgraduates. For these 208 records the ITT level was changed and the data was then validated and signed-off by the production team.
  • The proportion of postgraduate trainees with unknown degree class was higher this year than in previous years. To populate these missing fields, unique identifiers were used to match trainees from an alternative dataset to the cleaned record.

 

Trainees included in this release

We included a number of filters to the data received from ITT providers to ensure we capture only valid trainees.  We included:

  • trainees with valid records (they were not dormant, deferred or marked as a draft record)
  • trainees that did not leave their course within the first 90 days
  • trainees that were not excluded for other reasons (see below)

We identified final year trainees for this publication using the following filters: 

  • if they were recorded to have left in the 2019/20 academic year
  • where end dates were not recorded, we included only full-time postgraduate trainees who started in the 2019/20 academic year

 

Trainees excluded from this release

There are a number of trainees excluded from the mainstream ITT analysis who may be working towards QTS or another teaching qualification. The figures presented in this release do not include:

  • Non-supported trainees – we exclude a small number of trainees that the provider has indicated are not eligible for UK financial support and do not have a DfE allocated place. This includes overseas trainees not entitled to UK financial support; trainees on the School Direct salaried route undertaking a non-DfE-funded subject and/or employed at an independent school; or in situations when a School Direct Salaried trainee is undertaking a subject that would not normally be funded by DfE, but the provider is funding the trainee themselves outside of their DfE allocated places.

Some trainees are excluded from the mainstream underlying data sets but are included in their own separate underlying data sets for this publication.

  • Assessment only candidates – assessment only is for experienced teachers with a degree and those with a teaching qualification from different countries, who have not been awarded QTS in England. It allows teachers to do the necessary assessment to qualify for QTS without taking an ITT course.
  • Early years ITT – Trainees working towards early years teacher status (EYTS) are not included as mainstream trainees as they are not eligible for QTS. This programme focuses on pre-school initial teacher training. However, High Potential ITT (formerly known as Teach First) offer an early years programme working with children aged three to five years, which does lead to QTS; therefore, these trainees are included in the mainstream underlying datasets.

 

Measuring Employment

The Department uses internal administrative data sources to estimate how many final year trainees awarded QTS go on to employment in a state-funded school in England. Trainees in the ITT performance profiles in academic year 2019/20 are matched with the relevant school workforce census (SWC) to identify which trainees went on to teach in a state-funded English school in the year following qualification to produce provisional and then revised employment rates (see details below). The SWC is a snapshot of everyone working in a state-funded school in England taken in November each year. 

For this publication, we calculate two employment rates:

  1. A provisional employment rate for final year trainees in the 2019/20 academic year
  2. A revised employment rate for final year trainees in the 2018/19 academic year

Provisional employment rate: Departmental analysis has found that matching ITT trainee data to school workforce census data from the year following qualification does not fully capture how many trainees go onto employment because some teachers do not start in time to be recorded in that SWC, while others start up to a year later. We account for these teachers by applying an uplift to the 2019/20 employment figures to estimate a provisional employment rate for 2019/20. The uplift is derived by comparing with data from previous years to determine what proportion of new teachers employed during the year were not included in their first school workforce census but were captured in the following year’s census (the uplift applied for 2019/20 was around 27% of those not captured in the first year). 

Revised employment rate: We use the SWC data two years on from ITT completion to calculate a ‘revised’ employment rate that fully captures all trainees employed within 16 months of qualification. 

More information on the methodology used prior to the 2017/18 academic year (when the Department switched to using internal administrative data sources to estimate employment rates) and the rationale for the change in methodology can be found in the publication of the ITT performance profiles for academic year 2016/17.

 

The 2017/18 revised figures also include a correction made to the linking methodology in last year’s publication (academic year 2018/19).  In the performance profiles published in 2019 (for academic year 2017/18), we captured 364 trainees who appeared in the school workforce census prior to ITT completion (296 of which were in the SWC 2017/18). These 364 trainees were removed in the revised employment figures. The majority of those removed were on a School Direct Salaried route and so this is where the change in the revised figures is most apparent.

Official Statistics

These are Official Statistics and have been produced in line with the Code of Practice for Official Statistics. 

This can be broadly interpreted to mean that the statistics: 

  • meet identified user needs; 
  • are well explained and readily accessible; 
  • are produced according to sound methods; 
  • are managed impartially and objectively in the public interest. 

Once statistics have been designated as Official Statistics it is a statutory requirement that the Code of Practice shall continue to be observed. 

The Department has a set of statistical policies in line with the Code of Practice for Official Statistics.

Find out more about the standards we follow to produce these statistics through our Standards for official statistics published by DfE guidance.
