Rebuilding the Straight-Razor Unit
At a 1,500-hour program, the straight-razor shaving unit is scheduled for weeks 18–21. The incoming cohort has 12 students; the school has six mannequins, two shampoo sinks, one clinic chair approved for razor services, and two 45-minute theory blocks per week plus 3-hour clinic shifts. The inherited plan is a 30-slide lecture, one instructor demonstration, and live-client shaves in week 2. Last cohort, 9 of 15 students failed the first practical, most often for razor angle, thin or drying lather, poor skin stretching, and nicks near the jawline. Two current students have documented sharp-instrument anxiety; one has hand eczema and cannot tolerate repeated glove changes. The state practical requires safe setup, stropping, shave readiness, and sanitation. The instructor has four weeks, no extra budget, and a program director who wants live clients by week 3 to recover clinic revenue.
1. Using backward design, write three measurable outcomes for the straight-razor unit and match each to an assessment. Explain why these outcomes, not the inherited lecture topics, drive the plan.

Outcome 1: Given a mannequin and shaving products, the student will build a lather of acceptable consistency and apply it without thinning or drying during a two-pass shave, scored on a 5-point lather checklist. Assessment: station check before any blade touches skin. Outcome 2: The student will demonstrate razor angle, skin stretching, and stroke direction on a balloon or mannequin with zero nicks in a 5-minute timed performance, scored with a safety checklist. Assessment: safety gate; failure stops progression. Outcome 3: The student will complete a supervised live-client shave using clean technique, correct stropping and blade handling, and client communication, scored with the state-style practical rubric at 75% or better. Assessment: summative practical. Reasoning: Backward design starts from what the state practical and safe clinic practice require, not from slide topics. The inherited lecture may support these outcomes, but it cannot be the unit’s organizing structure. The outcomes are measurable because each names a condition, behavior, and criterion. They also sequence safety before service: lather and angle are prerequisites for live clients, so assessment must gate progression rather than simply follow it.
2. Sequence the four weeks and identify at least three safety gates that must be passed before a live client. Address the director’s request to have live clients by week 3.

Week 1: prerequisite reading and video; instructor demonstration with think-aloud; lather practice on a mannequin; razor handling without a blade; sanitation and bloodborne-pathogen review. Gate 1: lather checklist and hand-washing/station setup. Week 2: non-blade angle drills on a balloon or mannequin; stropping; skin stretching; one-pass mannequin shave. Gate 2: zero-nick balloon or mannequin performance and correct blade disposal. Week 3: supervised mannequin two-pass shave; selected live clients only for students who pass Gate 2; others rotate to lather, stropping, and observation. Gate 3: instructor check of setup, blade handling, and client communication before skin contact. Week 4: live-client shaves with debrief and remediation; summative practical. Director pressure: explain that putting every student on a live client in week 3 would convert a known failure pattern into a client-safety risk. Offer a compromise: a small number of live clients with students who pass the gates, while the rest do mannequin repetitions; track pass rates. If the director insists on all students, document the safety rationale and request additional supervision. The schedule should be driven by gates, not revenue.
3. How would you adjust for the two students with sharp-instrument anxiety and the student with hand eczema while preserving the safety standard?

Adjustments: For sharp-instrument anxiety, use graded exposure-first handle a razor without a blade, then a bladed razor on a balloon, then a mannequin, then a live client only after the same safety gate. Offer a private practice station and a pre-performance script; do not force a live client early. For hand eczema, confirm accommodations with the program’s disability and health protocol: nitrile gloves instead of latex, shorter glove-wearing blocks, fragrance-free soap, and a barrier cream if approved; allow the student to alternate lather and stropping tasks. The safety standard does not change: hand hygiene, glove changes, no double-dipping, and proper blade disposal are still required. If glove changes cause skin breakdown, the student may need a documented temporary restriction from live shaving, not a waiver of sanitation. Resource constraints: rotate six mannequins in two stations, use the two sinks for lather and cleanup, and keep the single clinic chair for gated live clients. This preserves equity because the criteria are the same; only the route and supports differ.
