The ECTS credits measure the total volume of work that the student should produce to complete, successfully, a period of studies that he/she has selected. Each ECTS credit has a value that is defined in accordance with the overall work that the subject represents. The same subject may have various classifications in the different courses.
Each year of a course in which the ECTS is implemented has 60 credits allocated, whilst one semester is equivalent to 30 ECTS credits.
There is not necessarily an arithmetic division by the number of subjects. The number of credits attributed to each one is not compulsorily linked to the number of teaching and practice hours of each subject in the respective course. They should also be related to the effort that the module requires, its importance in the course curriculum, its specific weighting factor and also its usefulness in the job market.
