The job gives it context.
The learning still needs structure.
Your apprentice follows an individual Training Plan agreed with you and Sigma. Theory is sequenced around prerequisites and the work they need to learn, then applied to real maintenance tasks under qualified supervision.
Learner guides, practice quizzes, audio resources where available and clear evidence templates give them something useful to work through between trainer sessions.
Knowledge tasks, practical observation and a competency conversation establish competence. Your supervisor verifies workplace evidence; Sigma’s assessor makes the competency decision.
