From Open Water Instructor (with Accelerated Decompression Procedures and the relevant technical diving qualification), you can start training to become a technical diving instructor.
BSAC technical courses must be conducted by appropriately qualified Instructors. In addition to basic instructor qualifications, Technical Instructors need to be experienced in the type of technical diving they are teaching.
The training and development of Technical Instructors is delivered by Instructor Trainers who are experienced Technical Instructors who also have received additional instruction and assessment as Instructor Trainers (either on BSAC ITS or with other technical training agencies). Further information is contained in BSAC Technical Standards:
Technical Instructors from other agencies
BSAC welcomes technical instructors from other agencies. Recognition and transfer of qualifications is by dedicated workshops which are tailored to the needs of the individual instructor.
BSAC Technical Standards has further detail on Alternative Agency Equivalence Recognition.
BSAC rebreather instructors can teach open circuit technical courses
A BSAC rebreather Instructor who holds an equivalent open circuit diver certification with the same depth and gas ratings may also teach a BSAC open circuit course at that level. For example: a MOD 2 CCR instructor who also holds Explorer Mixed Gas (XMG) Open circuit qualification may teach the XMG course.
