Bose is wrong, I'm afraid. There is no approved training program but refresher training, determined by an ATO, is required under EASA rules for renewal of an expired rating. The amount of training required will be determined by the ATO having evaluated the pilot's logbook and, if necessary, conducting a test in an FSTD. On completion of the training, the ATO should issue a certificate, which will be required by the competent authority when the renewal is applied for.
For each rating lapsed by more than one year but less than 7, a minimum of three training sessions will be required. There is, however, no definition of what constitutes a training session - three 10 minute ground briefings would fulfil the requirement as written.
