Sorry, inyoni, not true. Things are very different under JAR.
30 hours ground training and 15 hours flight training is the minimum for the holder of a non-JAA instructor rating/certificate, that includes instructors from JAA member states which have not yet fully implemented JAR-FCL1 (France, Germany, etc, etc.). After completing the mandatory training and passing the test with a FIE, you will get only a 'restricted' rating, allowing you to work under the supervision of a nominated FI for a minimum of 100 hours and until you have supervised 25 solo flights. Therafter, on the recommendation of the nominated FI, the restrictions will be removed.
As BlueLine says, GID 34 has all of the information that you need.
