European credit transfer and accumulation system (ECTS)
If you're moving inside Europe ECTS makes it much easier to get your studies recognised.
You can claim ECTS credits for each course you've successfully completed:
However, education institutions are free to decide how many ECTS credits their courses are worth.
If ECTS credits are not available for courses you've done in the past, you might have to apply for credential evaluation/recognition. This will help both you and your target university understand how your previous study relates to its courses.
Depending on the country, responsibility for evaluating your previous study will lie with the educational institution, the relevant education ministry or the national academic recognition or information centre.
In countries where there are no such centres, contact the ministry of education.
