Personnel who do not meet the Enlisted/Officer and TCCC-CMC student course requirements may become a TCCC-CLS Assistant Trainer and may assist with skills practice and lecture presentations. However, a fully qualified CLS Trainer must deliver or directly supervise all didactic (lecture) presentations. TCCC CLS Assistant Trainers are NOT authorized to formally assess skills or deliver unsupervised lecture presentations. The TCCC-CLS Course and the TCCC-CLS Train the Trainer Course are requirements to be a TCCC-CLS Assistant Trainer.
