The EIF Guidebook includes programmes that have at least preliminary evidence of achieving positive outcomes for children – which is equivalent to level 2 on our standards of evidence. Programmes that are ‘not level 2’ (or rated NL2) are not included in the Guidebook.
Previous versions of the EIF evidence standards included lower ratings of 0 and 1, where 1 indicated that a programme has a logic model and testable features of the kind that might be used to evaluate its impact at some point in the future. In our view, this was not a helpful distinction in terms of helping commissioners and others to understand what the evidence was saying about likely or possible impact. To reflect this, we have adapted our evidence standards to exclude specific conclusions about programmes that do not meet the level 2 threshold.
In its current form, the Guidebook provides information based on evidence of impact gathered through a formal evaluation process, and does not make judgments about the adequacy or correctness of logic models and programme designs. Programmes that do not have evidence are rated NL2 (‘not level 2’), rather an 0 or 1.

Unlike the cost rating, there is no level 5.
