Evaluate Cosmetologist candidates across 4 weighted areas: craft of the service, client care, standards and hygiene, and commercial awareness. Craft of the service leads at 35%, so test breadth across cutting, chemical services and finishing: balayage and foil weaving, keratin or relaxer timing, perms, formulating with Redken or Wella developer. Use the rubric to compare role-specific evidence consistently.

TL;DR
For craft of the service, look for evidence the candidate names formulations, developer volumes and processing times from memory; shows before and after work across textures, lengths and correction jobs. For client care, look for evidence the candidate describes documented consultations, sets honest expectations before mixing, and holds a named regular clientele who followed them between salons.
Apply the written 1–5 anchors to every answer, record the evidence behind each rating, and use the factor weights to reach a consistent overall assessment.

What to assess and how to score it
Review the evidence signals before interviewing. Then use the anchored descriptions—not instinct alone—to choose the score that best matches each answer.
