Question to the Ministry of Justice:

To ask the Secretary of State for Justice, pursuant to the Answer of 13 June 2019 to Question 262418, if he will publish the research referred to in that Answer.

The department seeks to deliver impact evaluations for all accredited programmes. However, the feasibility of an impact evaluation needs to be reviewed first in an evaluability study. The factors that are reviewed to determine whether an impact evaluation is possible include:

• The expected reduction in reoffending rate for the specific offender cohort, and the appropriate number of years over which we expect reductions in reoffending to occur;
• The number of programme completers required to detect this reduction (calculated using statistical power analysis); and
• The quality of the data and information available.

Evaluability studies ensure that the best possible evaluation approach is identified. Therefore, it is not possible to provide a single threshold for the number of participants in an accredited programme below which it would not have an impact evaluation carried out, as it will differ by programme.

The department is committed to publishing all research carried out in line with the Government Social Research guidelines.
