Best NCSO Practice Question Sites (2026)

Written and fact-checked by the NCSO Prep team, Alberta · Last reviewed 15 August 2026 · Sources

If you are hunting for the best NCSO practice questions, here is an honest, ranked review of every option worth knowing about in 2026 - including the ones we compete with.

The ranked list

1. NCSO Prep (ncsoprep.ca) - Best overall

The strongest option for most candidates. NCSO Prep offers a free legislation module with no credit card, all 10 module-specific practice pages, an interactive readiness calculator, a study plan generator, timed mock exams, and a single Readiness score across all modules. Every question is written originally from current Alberta OHS legislation and adopted standards, with an answer explanation and a citation to the source section. Pricing is $19/mo, $129/yr, or $199 lifetime CAD.

2. ConstructionTutor - Established option, paid only

ConstructionTutor is a legitimate, established provider of NCSO exam prep. It is a paid service and a reasonable choice for some learners. Compared to NCSO Prep, it does not offer a free legislation module, an interactive readiness calculator, or a study plan generator. If you already use it and it works for you, there is no reason to switch.

3. Stuvia - User-generated dumps, quality varies

Stuvia is a marketplace where anyone can upload a document and set a price. Quality varies wildly: content may be outdated, incomplete, or simply wrong, and it is not checked against current Alberta legislation. There are no answer explanations, no legislative references, and no module tracking. Some listings may include confidential real exam content, which is unethical and can lead to disqualification. Not recommended.

4. ACSA official materials - Official but limited practice questions

The Alberta Construction Safety Association publishes the NCSO Information Booklet and official program material, which is the authoritative source for exam facts, the 75% pass mark, the course list, and the experience requirement ([ACSA](https://www.youracsa.ca/ncso-hsa/national-construction-safety-officer-ncso/)). However, ACSA does not publish a large bank of practice questions, so most candidates pair the official material with a third-party prep platform.

5. YouTube NCSO prep channels - Free but unstructured

A number of YouTube channels offer free NCSO prep content. They can be a helpful supplement, but they are unstructured, rarely cover all 10 exam modules, and do not offer answer explanations with legislative citations, module tracking, or a readiness score. They are not enough on their own to reach the 75% pass mark.

How we ranked these

The NCSO exam requires a 75% pass mark and tests your understanding of how Alberta law applies on a real site ([ACSA Information Booklet](https://www.youracsa.ca/wp-content/uploads/NCSO-Information-Booklet-Feb-2025.pdf)). That means a good practice site needs: questions written from current Alberta legislation, answer explanations with citations, coverage of all 10 modules, a way to track readiness, and timed mock exams. We ranked each option against those criteria - including the ones we compete with.

Questions people ask

What is the best site for NCSO practice questions?

For most candidates, NCSO Prep is the best overall option because it offers a free legislation module, all 10 module-specific practice pages, a Readiness score, timed mock exams, and Alberta-specific content written from current legislation. ConstructionTutor is an established paid alternative.

Are free NCSO practice questions on YouTube enough to pass?

YouTube channels can be a helpful free supplement, but they are unstructured and rarely cover all 10 exam modules. They do not offer answer explanations with legislative citations, module tracking, or a readiness score, so they are not enough on their own to reach the 75% pass mark.

Does ACSA offer official NCSO practice questions?

ACSA publishes the NCSO Information Booklet and official program material, but it does not publish a large bank of practice questions. The official material is authoritative but limited in practice volume, which is why most candidates use a third-party prep platform alongside it.

Should I buy NCSO exam dumps from Stuvia?

No. Stuvia sells user-uploaded dumps that may be outdated, incomplete, or wrong, with no answer explanations and no check against current Alberta law. They may also include confidential real exam content, which is unethical and can lead to disqualification.

How many practice questions do I need to pass the NCSO exam?

There is no fixed number, but you should work enough questions across all 10 modules to reach a consistent Readiness score above the 75% pass mark. The NCSO exam tests understanding of how Alberta law applies on a real site, so quality questions with explanations matter more than raw quantity.
