CAIP defines three teaching formats: face-to-face, blended and distance
Depending on the degree of on-site attendance they require of students, university degrees can be classified as face-to-face, blended or distance.

The Institutional and Programme Assessment Committee (CAIP) has defined each of the three teaching formats. Among other things, it seeks to facilitate the classification of university degree courses in one or another format, as this information must be entered when presenting the validation report on any new degree to be implemented.
In short, the teaching formats have been defined as follows:
- Degrees in face-to-face format: those where on-site attendance is greater than two-thirds (2/3) of the teaching hours. Activities organised synchronously via the Internet can be considered equivalent to face-to-face teaching activities, although a number of requirements must be met.
- Degrees in blended format: those where on-site attendance is between one tenth (1/10) and two-thirds (2/3) of the teaching hours. Degrees that do not require the students' presence at the centre but that offer compulsory external work placements that exceed 1/3 of the ECTS credits of the degree, will be considered degrees in blended format.
- Degrees in distance format: those where the presence of students at the centre or other physical spaces is not required. In exceptional cases, up to 1/10 of the planned teaching hours may be face-to-face. These degrees may include external work placements or assessment systems (e.g. exams) that require attendance.
This proposal is in line with that established by the European Association for Quality Assurance in Higher Education (ENQA) and the General Secretariat for Universities in relation to teaching formats.
