- Class 1, 2, and 3 evaluations require data collection at only one point in time and only from the ICT Intervention sites and participants. This is often called a cross-sectional design.
- Class 4 evaluations usually require data collection at two or more points in time, and from both intervention participants and from a comparable control group. These are called "randomized experiments" if learners, classrooms or schools are randomly assigned to either the intervention or control group. They are called "quasi-experiments" if there is no random assignment but other means are used to match those in the intervention group and in the control group. Occasionally there will be more than one intervention group, for instance, when two levels of intensity or duration of the intervention are to be evaluated.
- <>Class 5 evaluations usually follow up several years later on the same groups used in a Class 4 evaluation, but they collect follow-up data on the later life application of the taught knowledge, attitudes, and skills only once.
- Class 6 evaluations usually rely heavily on developmental indicators collected by a country for a decade or more prior to the intervention and for a decade or more after the first several cohorts of participants have completed the intervention.
