ExploreAbout this exam
The ISED Basic credential is an entry-level qualification for people who work with radio apparatus under Canada's radiocommunication regulatory framework, administered through Innovation, Science and Economic Development Canada (ISED). Candidates typically include installers, service technicians, radio dealers, broadcast and two-way radio staff, and compliance or EMC test personnel who need a working command of how spectrum is allocated, how equipment is certified, and how interference is diagnosed and resolved. The exam samples broadly rather than deeply: expect questions on spectrum fundamentals such as frequency, wavelength, modulation and propagation; on the standards and certification process for radiocommunication apparatus; on interference sources, electromagnetic compatibility and mitigation techniques; on antenna systems, transmitter operation and installation practice; on measurement with spectrum analysers, power meters and test setups; and on safety, regulatory obligations and operational procedures. Because the domains are weighted fairly evenly, with standards and safety/regulatory content carrying the most weight, a candidate who studies only one area will struggle. Preparation works best as a structured pass through each domain using ISED's published regulatory documents and standards as primary reading, followed by practice questions that force you to apply definitions to concrete scenarios. Build a habit of converting units, reading decibels fluently, and reasoning about what a measurement or a symptom implies before you look at the answer choices.

What you'll study
About ISED Basic preparation
What format is the ISED Basic exam?
It is delivered as multiple-choice questions covering the six published domains. ISED publishes the current examination format, sitting arrangements and any administrative conditions on its own website, so check there before booking rather than relying on secondhand descriptions.
How long is the exam and what score do I need to pass?
The official body publishes the current time allowance and passing score, and these can change. Confirm both on the ISED site when you register. Do not plan your pacing around numbers quoted in forums or older study guides, which are frequently out of date.
How difficult is the exam for someone new to radio?
The individual concepts are not advanced, but the breadth is the challenge. You need comfortable arithmetic with decibels, frequency and wavelength, plus a working knowledge of certification and interference practice. Technicians with field experience usually find the practical domains easier and the regulatory detail harder.
In what order should I study the domains?
Start with RF fundamentals, because decibels, wavelength and modulation underpin everything else. Then take apparatus standards and certification, followed by interference and EMC. Finish with antennas and installation, measurement, and safety and regulatory obligations, revisiting the regulatory material last so it stays fresh.
What are the most common failure modes?
Candidates lose marks by confusing power and field-strength decibel references, misreading spectrum-analyser displays, and treating certification paperwork as memorisation rather than a process. Others skim interference mitigation and cannot match a symptom to a likely cause. Weak unit conversion and careless reading of negations in question stems also cost easy points.
Can I retake the exam if I fail?
Retake rules, waiting periods and any associated charges are set by ISED and published on its site. Check the current policy before you sit the exam so you know your options. If a retake is permitted, use the interval to target the domains where you were weakest rather than rereading everything.
Do I need practical experience before attempting it?
No formal experience is stated as a prerequisite, but hands-on familiarity helps enormously. If you lack it, substitute structured practice: work through measurement scenarios, sketch antenna and feedline setups, and read real equipment documentation so abstract terms map onto hardware you can picture.
How should I use practice questions?
Answer before looking at the explanation, then write down why each wrong option is wrong. Track errors by domain so you can see whether the gap is knowledge or misreading. Practice questions test recall and reasoning; they do not replace reading the actual regulatory documents and standards.
