What do the Performance courses (Coach 2, 3 and 4) require?

Prerequisites on the Tennis Canada Performance course page:

• Coach 2: CP2 or recognition of coaching competence; advanced feeding and skills; active TPA member; two provincially ranked U12 competitive players for portfolio assignments; the NCCP Make Ethical Decisions online evaluation if not already completed. About 20 days over a calendar year with four regroupings. Covers safe tennis environments, ethical decisions, athlete support in training, practice planning, supporting competition, performance analysis and program design and management.
• Coach 3: Coach 2 or recognition of coaching competence; advanced feeding and playing skills; active TPA member; two players at the Consolidation Stage for portfolio assignments; the NCCP Make Ethical Decisions Competition - Development evaluation if not completed. Coaches new to Canada need equivalent ITF-recognized certification and two years working with performance athletes.
• Coach 4: Coach 3; registration in the Canadian Sport Institute's Advanced Coaching Diploma; past or present work with internationally competing players, preferably ITF-ranked; access to a Performance or Transition to Pro player for portfolio assignments; active TPA member; one MED online evaluation; and a Vulnerable Sector Screening check before starting. Takes two years.

Minimum playing level: 5.5 for Coach 2 and Coach 3. The Tennis Canada pages give differing minimum ages for these courses (Coach 2: 20 or 21; Coach 3: 21; Coach 4: 21 or 25), so the exact figures are not settled by the source.
