Exam Overview
The Certified EC-Council Instructor (C|EI) certification, associated with exam code 312-75, is EC-Council's credential for professionals who wish to become authorized instructors delivering EC-Council's suite of cybersecurity certification programs — including CEH, CHFI, ECSA, LPT, CND, and others. The certification validates that a candidate possesses the pedagogical skills required to effectively teach technical security content to adult learners, covering core instructional competencies such as establishing credibility, managing the learning environment, delivering presentations, applying questioning techniques, and evaluating learner performance.
The C|EI program is built around adult learning principles and instructional design methodology, ensuring that certified instructors can adapt EC-Council's standardized course materials to diverse learner audiences. Earning the C|EI credential is a gateway to becoming an EC-Council Subject Matter Expert (SME), a designation reserved for professionals who contribute to curriculum development and deliver authoritative training content within the EC-Council ecosystem. Only individuals who meet stringent application and exam requirements are granted C|EI status, reflecting EC-Council's commitment to quality instruction across its Accredited Training Center (ATC) network.
Who Should Take This Exam
The C|EI is designed for experienced cybersecurity professionals and trainers who wish to deliver official EC-Council certification courses through authorized training channels. Ideal candidates include independent security trainers, corporate training managers, academic instructors at technical institutions, and staff at EC-Council Accredited Training Centers (ATCs) who are already certified in the EC-Council program they intend to teach — for example, a Certified Ethical Hacker (CEH) who wants to train others toward the CEH credential.
Candidates should have an established background in hands-on security work and a demonstrated training or teaching history. This certification is not suited for entry-level professionals; it targets individuals with meaningful industry experience who are ready to transition into or formalize a role as a professional cybersecurity educator within the EC-Council framework.
Prerequisites
Applicants must hold an active, current EC-Council certification in each program they intend to teach — for instance, candidates wishing to instruct CEH courses must themselves hold a valid CEH credential. All EC-Council certifications must be in good standing, with Continuing Education (ECE) credits kept current through the EC-Council Aspen Portal.
Candidates who do not already hold instructor credentials from another recognized body (such as CompTIA CTT+, Microsoft MCT, Cisco, PECB, Oracle, or VMware) must submit an experience letter on official organizational letterhead demonstrating a minimum of two years of active training or teaching involvement. Additionally, applicants must secure an endorsement from an EC-Council Accredited Training Center (ATC), though EC-Council may endorse the application at its own discretion if no ATC sponsor is available. Technical hands-on expertise with security technologies is also expected.
Exam Format
The CEI exam (312-75) consists of 50 multiple-choice questions and must be completed within 120 minutes. The exam is delivered through EC-Council's official exam portal (ECC Exam Center). Candidates must achieve a passing score of 70% to earn the certification.
The exam is scenario-based in nature, testing practical knowledge of instructional delivery rather than purely technical security content. It assesses a candidate's understanding of adult learning principles, instructional design, classroom management, and communication techniques in the context of delivering EC-Council certification courseware. No unscored or survey questions have been publicly documented for this exam.

Study Tips
- Obtain the official C|EI Instructor Manual through an EC-Council Accredited Training Center (ATC) — this is the primary study resource aligned directly to exam objectives and covers all domains tested on the 312-75 exam.
- Review EC-Council's published exam objectives for 312-75 carefully and map each objective to practical instructional scenarios you have encountered or can envision, since the exam uses scenario-based questions.
- Study adult learning theory fundamentals — particularly Malcolm Knowles' andragogy principles — as the exam heavily tests the application of adult education concepts to technical cybersecurity training delivery.
- Take timed practice tests using reputable third-party question banks (such as those on EDUSUM) to identify weak domains and acclimatize to the 50-question, 120-minute format before exam day.
- Leverage any experience you have delivering other technical certifications (e.g., CompTIA, Microsoft, Cisco) to ground your answers in real instructional situations; the exam rewards applied, not theoretical, knowledge.
- Review EC-Council's ATC policies, instructor agreements, and code of conduct documentation, as exam questions may address CEI responsibilities, boundaries of the instructor role, and compliance with EC-Council's program standards.
- If possible, shadow or co-instruct with an existing C|EI at an Accredited Training Center before sitting the exam — observing certified instructors deliver EC-Council content provides direct insight into the competencies assessed.
Career Benefits
Earning the C|EI credential authorizes professionals to deliver EC-Council's globally recognized cybersecurity certification programs — including the Certified Ethical Hacker (CEH), Computer Hacking Forensic Investigator (CHFI), Certified Network Defender (CND), and EC-Council Certified Security Analyst (ECSA) — through the worldwide ATC network. This opens direct revenue opportunities as an authorized trainer, with cybersecurity instructor rates typically ranging from $1,000 to $3,000+ per training day depending on geography and specialization. Certified instructors also gain access to EC-Council's secured instructor resource portal, which includes up-to-date presentation materials, lab environments, and course videos.
Beyond direct training income, the C|EI designation enhances professional credibility within the cybersecurity education sector, differentiating holders from uncredentialed trainers when competing for corporate training contracts or academic positions. C|EI holders may also be considered for EC-Council's Subject Matter Expert (SME) program, contributing to curriculum development and exam authoring. As demand for skilled cybersecurity professionals — and the training programs that produce them — continues to grow globally, the C|EI credential positions holders at the intersection of technical expertise and professional instruction.
Sample Questions
5 sample questions with answers and explanations. Start a practice session to test yourself across all 611 questions.
Preview — answers shown1. An instructor is teaching about SQL injection and wants students to determine the underlying relationship between input validation failures and database vulnerabilities. Which level of Bloom's Revised Taxonomy does this represent? (Select one!)
AEvaluate level making judgments based on criteria
BRemember level requiring retrieval of facts
CAnalyze level breaking materials into components
DUnderstand level determining meaning of concepts
Explanation
The Analyze level involves breaking materials into component parts and determining relationships between elements. Identifying how input validation failures relate to database vulnerabilities requires analyzing the connection between components. Remember involves recalling facts. Understand means determining meaning without breaking down components. Evaluate involves making judgments based on criteria and standards.
2. A CEI instructor is evaluating a multiple-choice test item and calculates that 85 percent of students answered it correctly. The item has a difficulty index (p) of 0.85. According to item analysis principles, what does this indicate about the test question? (Select one!)
AThe item is too difficult and should be revised to make it easier
BThe item is too easy and may not effectively discriminate between high and low performers
CThe item has negative discrimination and should be removed immediately
DThe item has perfect difficulty and should not be changed
Explanation
Item analysis uses the difficulty index (p) ranging from 0.0 to 1.0, calculated as number correct divided by total test-takers. Higher p values indicate easier items. The ideal difficulty index is 0.30 to 0.70. A difficulty index of 0.85 indicates the item is too easy, as 85 percent of students answered correctly. Easy items may not effectively discriminate between high and low performers. The item is easy, not difficult, so revision should make it more challenging, not easier. The difficulty is outside ideal range, not perfect. Difficulty index does not indicate negative discrimination, which is measured by the discrimination index .
3. An instructor is creating a summative assessment for the final day of CND training. The assessment must determine if students have achieved mastery of specific learning objectives with a predetermined passing score of 70%. Which assessment type should the instructor design? (Select one!)
ADiagnostic assessment identifying existing knowledge before instruction begins
BFormative assessment providing ongoing feedback during learning process
CCriterion-referenced assessment measuring performance against predetermined standards
DNorm-referenced assessment comparing students to each other with percentile ranking
Explanation
Criterion-referenced assessments measure student performance against predetermined standards or criteria, such as achieving 70% mastery of learning objectives. This approach determines pass or fail based on meeting established criteria. Norm-referenced assessments compare students to each other and produce percentile rankings rather than measuring against absolute standards. Formative assessments occur during instruction for ongoing monitoring, not at the end as summative evaluation. Diagnostic assessments are pre-instruction tools to identify existing knowledge and skill gaps before training begins.
4. A corporate client requests a customized ECIH course focusing exclusively on ransomware incident response. The client wants the instructor to remove modules on DDoS attacks and insider threats to fit the training into 2 days instead of the standard 3-day, 24-hour program. How should the CEI respond according to EC-Council courseware policies? (Select one!)
ARefuse the request because key learning objectives should not be changed without EC-Council approval, and refer the client to courseware designers
BAccept the request but require the client to sign a waiver acknowledging the modified curriculum
CAgree to the customization since client needs should drive training content selection
DDeliver the modified 2-day course but supplement with additional ransomware case studies to maintain quality
Explanation
EC-Council course delivery requirements explicitly state that key learning objectives should not be changed without approval. If objectives don't address client needs, instructors must refer clients to courseware designers or training managers rather than independently modifying core curriculum. ECIH is a 3-day, 24-hour program with defined learning outcomes. While instructors can provide updated statistics or supplemental examples, removing entire modules alters the course structure and certification alignment. Simply agreeing to customization violates policy. Supplementing with case studies doesn't address the removal of required content. Waivers don't grant authority to modify approved curriculum without EC-Council authorization.
5. An instructor notices during a penetration testing lab that a participant named Robert quietly observes others, takes extensive notes, reviews documentation thoroughly, and hesitates before attempting configurations. According to Honey and Mumford's learning styles, which style does Robert demonstrate and what instructional adjustments should the instructor make? (Select one!)
AActivist style; provide more brainstorming sessions and group problem-solving activities
BPragmatist style; provide more practical case studies and immediate real-world applications
CTheorist style; present more logical models, systems thinking, and pattern analysis exercises
DReflector style; allow adequate thinking time, avoid pressuring for immediate action, and provide opportunities to observe demonstrations before attempting tasks
Explanation
Honey and Mumford's learning styles, based on Kolb's cycle, include Activist, Reflector, Theorist, and Pragmatist. Reflectors are cautious individuals who stand back, observe from sidelines, and think before acting. They prefer time to think, watching others first, reviewing information, and conducting research. They dislike quick decisions, pressure situations, and tight deadlines. Robert's behaviors of quiet observation, extensive note-taking, thorough documentation review, and hesitation before attempting tasks are classic Reflector characteristics. Instructors should provide observation opportunities, avoid rushing, and allow processing time. Activists are impulsive and act first, opposite of Robert's careful approach. Theorists prefer logical analysis and models. Pragmatists are practical experimenters who test ideas immediately.
