Narrative:

Training was in progress. An aircraft was on a vector for a downwind for an ILS approach. The aircraft was at 3;000 feet and was in an area where the minimum vectoring altitude (MVA) is 2;300 feet. The minimum altitude for the ILS is 2;400 feet. The trainee descended the aircraft to 2;400 feet. The trainee got distracted and forgot to turn the aircraft onto its base leg and it got close to an area where the MVA is 3;000 feet. The trainee noticed and issued a turn and a climb away from the higher MVA area; but the aircraft entered the 3;000 foot MVA before its mode C indicated a climb. I don't think interjecting earlier would have been effective training and the closest the aircraft was to the obstruction was approximately 2.8 NM laterally and 650 ft. Vertically.
