NIC Barber Instructor cheat sheet

Maslow's hierarchy order: physiological, safety, belonging, esteem, self-actualization; unmet lower needs block learning readiness.

Bloom's taxonomy (revised) order: remember, understand, apply, analyze, evaluate, create; barbering psychomotor skills sit mainly at apply.

Four stages of psychomotor learning: observation, imitation, practice, adaptation; learners need demonstration before imitation.

Retention after 24 hours is roughly 10% of what is read, 20% heard, 30% seen, 50% seen and heard, 90% said and done.

VARK modalities: visual, auditory, read/write, kinesthetic; most barbering tasks are taught kinesthetically with visual modeling.

Reinforcement timing rule: immediate praise strengthens a new skill faster than delayed praise; intermittent reinforcement sustains it.

Chunking rule: present no more than 5-7 new steps at once; working memory holds about 7 items.

Transfer of learning occurs when practice conditions match the real work setting (same chair, tools, and client draping).

Formative assessment checks learning during instruction; summative assessment grades it at the end.

Lesson plan sequence: objectives, materials, anticipatory set, demonstration, guided practice, independent practice, evaluation, closure.

Objectives must be measurable: use action verbs (list, demonstrate, perform) rather than vague verbs (know, understand).

Clock-hour programs track attendance and completion in hours; credit-hour programs track Carnegie units of contact time.

Task analysis breaks a skill into ordered sub-steps, e.g., clipper-over-comb into position, guard, angle, stroke, blend.

Demonstration length rule: keep a single demo under about 10-15 minutes, then hand control to learners for practice.

Materials checklist should cover mannequin or model, tools, disinfectant, capes, towels, and safety equipment before class starts.

Evaluation plan should state the grading instrument (rubric, checklist, or practical exam) before instruction begins.

Lesson pacing should move from simple to complex and from slow speed to production speed.

Proximity control: moving near an off-task student usually corrects behavior without verbal interruption.

Behavior escalation order: proximity, private prompt, redirect, documented consequence, referral.

Rubric scoring rule: define 3-4 performance levels and state observable criteria for each level before grading.

Competency threshold: a passing practical score typically requires meeting every critical safety step, not an average.

Documentation rule: record absences, tardies, and remediation in writing with dates; verbal warnings alone are not defensible.

Clinical floor ratio: state law or school policy sets the maximum student-to-instructor ratio on the clinic floor; verify the current rule.

Feedback rule: give corrective feedback privately and immediately after the observed performance, not at the end of the term.

Grade appeal path: instructor record, program director review, then written institutional appeal.

Hair growth stages: anagen (active growth), catagen (transition), telogen (resting/shedding); scalp hair grows roughly 0.3-0.4 mm per day.

Hair texture categories: fine, medium, coarse; density categories: thin, medium, thick; porosity: low, normal, high.

Cutting angles: 0 degrees creates a solid form or one-length line; 45 degrees creates a graduated form; 90 degrees creates a uniform layer.

Elevation rule: the higher the elevation, the more the hair is layered and the shorter the outer lengths become.

Clipper-over-comb requires comb teeth held flat against the head with the blade moving only on the comb's flat surface.

Taper vs. fade: a taper leaves visible weight at the nape and sides; a fade blends gradually down to the skin.

Razor cutting uses a cutting comb and a guarded razor; the blade angle stays low (about 30 degrees) to avoid digging.

Beard shaping rule: establish the neckline just above the Adam's apple and the cheek line from natural hairline to natural hairline.

Shampoo water temperature: warm water (about 100-105 F) opens the cuticle; cool water closes it and adds shine.

Cleaning removes visible debris; disinfection destroys most pathogens on nonporous surfaces; sterilization destroys all microbial life including spores.

EPA-registered hospital-grade disinfectant must be mixed and used per label contact time, typically 10 minutes for immersion.

Implements that contact blood or broken skin are single-use or must be sterilized with an autoclave at 250 F and 15 psi for 15-30 minutes.

Blood spill rule: stop the service, don gloves, clean the area, disinfect with an EPA-registered tuberculocidal product, and dispose of contaminated items in a sealed bag.

Handwashing is at least 20 seconds with soap and warm water; alcohol-based sanitizer is not a substitute for visibly soiled hands.

Porous items (towels, capes, neck strips) cannot be disinfected and must be laundered or discarded after each client.

Electrical safety: keep cords away from water, do not use tools with frayed cords, and unplug before cleaning.

MSDS/SDS must be on file for every chemical in the shop and accessible to workers.

Scope of practice rule: barbers perform services only within the licensed scope; chemical or medical procedures outside it are referred out.

Client record rule: keep service records, patch test results, and consent notes confidential; release only with written client authorization.

Conflict of interest: an instructor may not grade or evaluate a family member or someone with a financial relationship in the same cohort.

Patch test timing: perform 24-48 hours before a color or chemical service; document the result in the client record.

Pricing formula: service price must cover product cost plus labor time plus overhead plus profit margin.

Retail profit rule: retail products typically carry a higher margin than services; commission plans should state whether retail counts.

Booth rental vs. employee: renters set their own hours and pay rent; employees are scheduled and receive wages and payroll taxes withheld.

Advertising must not guarantee results or make medical claims; testimonials require written permission.

Licensure rule: barbers, shops, and instructors must hold current state licenses; licenses are posted visibly at the workstation or shop.

Continuing education: many states require a set number of CE hours per renewal cycle, often including sanitation and infection control.

Shop license inspection: the state board inspects sanitation, equipment, and records; failing an inspection can trigger re-inspection fees or closure.

Reciprocity rule: license transfer between states depends on the receiving state's requirements; endorsement is not automatic.

Minors: parental or guardian consent is typically required for chemical services on clients under the age of majority.

Record retention: shop and client records must be kept for the period the state board specifies; verify the current statute.

Unlicensed practice is a criminal or civil violation; allowing an unlicensed person to perform services exposes the shop license to discipline.

Display requirements: the state consumer complaint notice and license certificates are posted where clients can see them.
