Iran Nezam Electrical Supervision Exam

It supports the professional competency route toward an employment license (پروانه اشتغال) in electrical engineering, which is what lets you legally design and supervise building electrical installations. The organization sets the exact scope of duties tied to each license grade, so check its current regulations rather than relying on secondhand descriptions.

It is a Persian-language, multiple-choice exam taken on computer at designated Iranian testing centers. Expect four-option items, some conceptual and some requiring calculation. Because many items hinge on exact code values, practice reading clause text carefully rather than skimming for the general idea.

The Construction Engineering Organization publishes the current question count, time allowance and passing threshold for each exam period in its official announcement. Those figures change between administrations, so confirm them on the organization's own site before you plan your pacing strategy.

The difficulty is breadth plus precision. Common failure modes: memorizing formulas but not knowing which code clause governs a detail; ignoring unit conversions in derating and voltage-drop problems; and running out of time because calculation items were attempted before quick code-recall items. Practicing mixed sets under a clock exposes all three.

Retake rules, waiting periods and any limits on attempts are set by the Construction Engineering Organization and can be revised. Check its current announcement for the exam period you intend to sit. Do not assume the previous cycle's rules still apply, and keep your registration documents ready so a retake is not delayed.

Start with codes and standards plus wiring methods, because those underpin everything else. Then move to protection, grounding and load calculations, where the numeric work lives. Finish with special installations and professional practice, which are lighter on math but easy marks if you read the regulations once, carefully, near the end.

Use the actual standard texts. Summaries help you navigate, but exam items frequently test precise thresholds, tables and exceptions that summaries drop. Keep the national building code electrical section and the electrical installations standard at hand while solving problems, and annotate the tables you use most.

Enough that feeder sizing, demand factors, derating and voltage drop become routine rather than puzzles. Work from real panel schedules and single-line diagrams, not only textbook exercises. Aim to solve each calculation type repeatedly until you can set up the equation without hesitating over which correction factors apply.
