How we keep your study material current

You put time, money and attention into preparing for your contractor exam, often after a full day of work. That effort should build knowledge you can use. An outdated fee can leave you budgeting for the wrong amount, an outdated code answer sends your study time in the wrong direction, and a retake means more time and money.

For us, an explanation is only useful while the rule behind it is still current. Rules, fees and code editions change, and a lot of exam prep does not keep up. So we check official sources for changes automatically and regularly, and a person makes every final check and change. Keeping our material current is part of earning your trust.

What a check looks like

A few examples of what happens behind our guides and practice questions:

• A new code edition takes effect. We review the questions that cite that code against the edition CSLB lists for the exam, and update the questions and explanations that changed.
• An official page changes a fee or a requirement. Our source watch flags it, a person confirms it, and the new value appears in every guide that uses it.
• A learner reports a question. We check it against the source. If it is wrong or unclear, we fix the question or its explanation.

When we finish a notable check, we post a short update in our Resources feed.

Studying for a CSLB exam: how does Test2Pro keep its content current?

We start from official sources: CSLB pages and publications, including the exam study guides, PSI information for candidates, and the code editions CSLB lists for each exam.

California updates its building codes every three years. The edition in effect now is the 2025 California Building Standards Code, in effect since January 1, 2026. Fees, forms and rules can change in between, so checking the code edition alone is not enough.

Our source watch is an automated system. It regularly checks these official pages for changes and alerts our team when something changes. It never changes anything on our site by itself. A person always makes the final check and the final change.

The edition and the date above are facts we track this way. When a new edition takes effect, our source watch flags it, we confirm it, and both values update here and in every guide that uses them.

Choosing exam prep: how do I avoid studying outdated material?

Codes and rules change, and many courses and books fall behind: they keep teaching older editions and old practices.

Our questions keep improving. We follow the code edition CSLB lists for each exam and keep track of new editions as they take effect. A new edition taking effect is a reason to check your exam's references, not proof that every exam has switched.

Practicing for a CSLB exam: who checks the questions, and against what?

We write our own practice questions. They are not questions from the CSLB or PSI exams. We organize them by the topic areas CSLB publishes for each exam, so your results show which areas need more work.

When a question depends on a code citation, we check it against the code edition CSLB lists for that exam. California-licensed contractors review our study material. Notable checks go into the Resources feed.

Reading our pages: what do the check dates mean?

• Under a table of facts, a line says "Checked against official sources on" a date. That is the oldest date a person checked any value in the table, so every value in it was checked on that date or later. If a value has not been checked yet, the line says so.
• A fact in the text: hover over the value, or move to it with the keyboard, to see when a person last checked it and which official source it comes from. On a phone, tap it to jump to its source.
• "Sources & checks" at the end of a guide lists each official source with the date a person last checked the information we took from it.
• "Question bank last updated" with a month, on course pages: the latest change to that exam's questions. It does not mean every question was reviewed that month.

A check date tells you when we reviewed something. It cannot promise that the source has not changed since.

Using our material: what if an official rule changed before we caught it?

There can be a gap between an official change and our update. If our page and an official source disagree, the official source is right. Before you act on something important, open the official source we link to and check it there.

Found a wrong answer: how do I tell Test2Pro?

If something in our questions or guides looks wrong, or you are simply not sure about it, tell us. You don't need to know the right answer to raise it. Use Report question next to any practice question, or the Contact page for anything else, and mention the page or the question.

We check what you send, and a fix helps everyone who studies with us.
