To emphasise the developmental role of the evaluations, the Council sees that there is no reason to impose a uniform model on all evaluations. There are thus differences in the ways in which the evaluation projects are carried out. The duration of the programme and thematic evaluations varies from 9 to 12 months.
Institutional evaluations tend to take more time.
The appraisal of the evaluation is usually carried out and the focus defined by a steering committee. The steering committee does not take part in the evaluation itself but it plans, coordinates and follows up the implementation of the project. The accreditation of the polytechnics is organised by the Council and its Accreditation Subcommittee. The steering committee consists generally of 4 to 5 members. If this phase is required, it takes place before the appointment of the steering committee.
