10. Conclusion

What You've Covered

Phase 1 established the foundational framework: why the exam exists (public protection), and what scope of practice means in practice. Every question on the exam flows from these two concepts.

Phases 2 and 3 covered Safety and Infection Control — your single most important investment of study time at 40% of the exam. You learned the three decontamination levels, EPA disinfectant requirements, single-use vs. multi-use rules, exposure incident protocols, workplace safety standards, and the roles of OSHA, EPA, and FDA.

Phase 4 covered skin structure and the client consultation process, including how to identify and respond to skin conditions and contraindications.

Phase 5 applied that foundation to facial treatments — the basic facial sequence, electrical devices and their contraindications, and cosmetic chemistry basics.

Phases 6 and 7 covered hair removal and makeup application, with heavy emphasis on the infection control protocols specific to each service.

Next Steps

1. Take the PSI official practice test at psionlinestore.com — it mirrors the actual exam format
2. Review the content areas where you answered questions incorrectly in this guide; use the Reflection Questions as self-tests
3. Use the flashcards and practice questions generated from this guide for active recall practice
4. Re-read the official TTG before your exam date to ensure no procedural requirements have changed

Good luck. The exam tests whether you can protect your clients — and you now have the knowledge to do exactly that.
