What the NIC electrology examinations cover
The National-Interstate Council of State Boards of Cosmetology (NIC) develops licensure examinations for electrology. Your result supports licensure; your state decides which examinations and sections you must take.
Two current bulletins define the content: the National Electrology Theory Examination CIB and the National Electrology Practical Examination CIB. Both carry an effective date of June 1, 2018 and a revision date of January 1, 2026. Always download the current bulletin from NIC or your examination provider before testing, because the bulletin controls the version you are tested against.
NIC publishes bulletins for written, practical, and written practical formats, and its practical CIB includes additional service sections that some jurisdictions add. The practical bulletin states directly that you should check with your state regulatory agency or examination vendor to learn which additional sections your state requires. State requirements are separate from passing an examination: each state sets its own licensing path.

Theory exam format and how it is scored
The theory examination allows 90 minutes and contains 85 items, of which 75 are weighted toward your final score. Scientific Concepts carries 45% of scored content and Electrology Procedures and Services carries 55%.
The ten non-weighted items do not contribute to your result, so expect a few questions that feel unfamiliar and answer every item anyway. Because only 75 items are scored, the published percentages describe scored content, not all 85 questions.
Here is an original practice calculation, not an actual exam question, to make the weighting concrete.
Original practice exercise
Assume the published domain weights apply to the 75 scored items. Approximately how many scored items come from Scientific Concepts, and how many of the 85 total items should you expect to be unscored?
Show answer
About 34 scored items from Scientific Concepts (75 × 0.45 = 33.75), roughly 41 from Procedures and Services, and 10 of the 85 total items are unscored.
The theory CIB states the exam contains 85 items with 75 weighted toward the final score and gives Scientific Concepts a 45% share. The assumption stated in the prompt is that percentages apply to scored items only, which is what the bulletin describes. Subtracting 33.75 from 75 leaves about 41 for the 55% domain, and 85 − 75 = 10 unscored items. The rounding is expected because item counts must be whole numbers.
| Theory domain | Share of scored items | Main topics per the CIB |
|---|---|---|
| Scientific Concepts | 45% | Infection control and safety, anatomy and physiology, basic concepts of electricity and modalities |
| Electrology Procedures and Services | 55% | Consultation, analysis and documentation, items utilized, electrolysis procedures and post-service processes |

Theory content: what each domain expects
The theory CIB publishes a detailed content outline. Use it as your checklist: if a topic is not in the outline, it is background reading, not tested content.
Under Scientific Concepts, the outline covers how diseases and infections are caused and transmitted; the levels of infection control, including cleaning and sanitation, disinfection, sterilization, and contamination and cross-contamination; blood exposure procedures; and the requirements of agencies such as CDC, OSHA, EPA, and FDA. Anatomy topics include the structure and functions of the skin, the structure and growth cycle of hair, and the nervous, muscular, circulatory, and endocrine systems, plus signs and symptoms of skin and hair conditions. Electricity topics include electrical characteristics and measurement, direct and alternating currents, the modalities of electrolysis (galvanic, anaphoresis, cataphoresis, thermolysis, and blend), and electrical safety principles.
Under Electrology Procedures and Services, the outline covers client consultation, skin and hair analysis, contraindications specific to electrolysis, how hair removal methods such as waxing, depilatories, and laser differ, product and method selection, and record keeping including service history, medical history, and release forms. It also covers the purpose and function of equipment, implements, and supplies used during services, electrolysis procedures including client preparation, probe selection, insertion, depth, and angle, and post-service processes including cataphoresis and aftercare.
The bulletin includes five official sample questions with an answer key, and they show the expected style: single-best-answer items with four options, testing definitions, mechanism-linked reasoning, and agency recognition. Study the references listed in the CIB, dated January 1, 2026, in their most current editions, since those editions were used to write the items.

Practical exam: seven core sections and their timing
The practical examination has seven core domain sections based on a national job analysis. You demonstrate thermolysis, blend, galvanic, cataphoresis, and a blood exposure procedure on a live model, with two separate work area setups.
You bring one live model, but the exam introduces a new client partway through, so you perform more than one full client setup. You must bring an electrology machine labeled in English by the manufacturer that is capable of thermolysis, galvanic, blend, and cataphoresis, plus a magnifying device and a light source. Sharps containers are provided on site; you bring three containers labeled for items to be disinfected, soiled linens, and trash.
Timing is per section and announced by the proctor. If you finish early, raise your hand and step back; when the timer sounds, everyone stops working immediately. Mannequin rules are state-specific: where a head is required, it must be full size, approved in advance, and not premarked or presectioned.
Test the labeling rules with this original scenario before you pack your kit.
Original practice exercise
You want to save space in your kit, so you pour your disinfectant into a small spray bottle and attach a handwritten English label reading DISINFECTANT. Your wipes stay home. Is this kit acceptable for the practical examination, and why or why not?
Show answer
No. The kit would not be acceptable.
The practical CIB states that disinfectant and aerosol sprays are not allowed in the testing environment, and that EPA-registered disinfectant wipes demonstrating bactericidal, fungicidal, and virucidal properties must be used. Original manufacturer labels are required for disinfectants and hand sanitizers, and where an original label is required, no handwritten labeling is permitted. A transferred liquid with a handwritten label fails on all three points. Pack the original wipes container with its manufacturer label intact.
| Core section | Time | Key evaluated work |
|---|---|---|
| 1. Work area preparation and set up of supplies | 15 minutes | Disinfect work areas and equipment with EPA-registered hospital-grade product, sanitize hands, English labels, correct disposal |
| 2. Thermolysis | 10 + 5 minutes | Hair removal on the upper lip, safe implement and equipment use, skin assessment, then concluding disposal |
| 3. Prepare work area for new client | 15 minutes | Full re-setup of universal supplies for the new client and the remaining sections |
| 4. Blend method | 10 minutes | Hair removal on the leg, safe use, skin assessment, correct disposal |
| 5. Galvanic method | 10 minutes | Hair removal on the arm, safe use, skin assessment, correct disposal |
| 6. Cataphoresis | 5 minutes | Cataphoresis on the previously treated galvanic area, correct disposal |
| 7. Blood exposure procedure | 10 minutes | Simulated minor cut scenario: gloves, antiseptic cleaning, absorbent secured dressing, disposal of contaminated supplies |

Test-day conduct and safety rules
The practical exam evaluates you continuously, and specific failures have stated consequences: not following infection control or leaving the work area unsafe can produce a failing score or removal, and mishandling a blood exposure may result in dismissal.
Standardized administration rules apply to both formats. Proctors and examiners do not speak with candidates except for verbal instructions or emergencies; in the practical, requests for help are answered only with statements such as doing the best you can with what you have or doing as you were taught. Practical verbal instructions are read twice, and all practical examinations are administered in English.
Prohibited items include phones, watches of any kind, other electronic or recording devices, printed materials, handwritten notes, and personal items not needed for the exam. Communicating with other candidates or exhibiting disruptive behavior risks immediate dismissal and a report to the authorities. You must obtain permission to leave the examination area, and picture ID is required to re-enter.
The electrology practical adds specific expectations: you are evaluated on correct designation of materials for disposal throughout every section, single-use labeling of products is not allowed and can fail you, and you must address unsafe conditions immediately. The blood exposure section is a simulation with a defined scenario, but the bulletin also tells you to obtain the most current blood exposure procedures and any addenda from your examination provider or state before test day.

How to prepare and what to confirm next
Build your plan from the two CIBs: study theory topics in proportion to their published weights, and rehearse the seven practical sections in order with compliant supplies under supervision.
For theory, work through the content outline topic by topic, then use the official sample questions to check your answer style. The CIB lists the standard and supplemental references used to develop the exams, with Milady and Pivot Point titles and a reference date of January 1, 2026; study the most current editions because those were used to write test material.
For the practical, the CIB provides a suggested supply list, but you remain responsible for bringing everything you need in working order. Hands-on skill must be built under qualified supervision in an authorized setting; passing a paper guide or a practice run cannot substitute for that training. NIC also publishes practice exams and exam overviews on its site, which are useful for pacing.
Before booking, confirm the items the bulletins deliberately leave to your state: which examinations and additional sections apply, model and mannequin requirements, blood exposure procedure versions, scheduling, fees, and eligibility. Your state board or examination vendor is the authoritative source for each.
- Download the current theory and practical CIBs and read every part, including supply lists
- Verify your state's required sections, model rules, and any addenda with your board or vendor
- Study the listed references in their current editions, weighting Scientific Concepts at 45% and Procedures at 55% of scored theory items
- Assemble a labeled, compliant kit: EPA-registered wipes, English labels, three disposal containers, a four-method machine, magnification, and light source
- Rehearse all seven practical sections in order with one live model and two full client setups, under supervision
