Editorial policy

Hayzum publishes calculators and guides to help Australian students understand ATAR, grades, and how senior secondary results work. This page explains how we research, write, and maintain that content, and what you can expect from us as a reader.

Who writes our content?

Content on Hayzum is prepared by the Hayzum editorial team. We research each topic using official sources, state and territory tertiary admissions centres (such as UAC, VTAC, QTAC, TISC, SATAC and others), curriculum authorities, and published scaling reports before writing a single word. Where a topic touches on personal academic or financial decisions, we write to inform, not to instruct. We say clearly where a school, university, or admissions centre is the better authority.

How we handle accuracy

ATAR scaling, subject rules, and entry requirements change from year to year and differ between states. We do our best to keep every ATAR calculator and guide current, and we note the year a scaling table or rule applies to wherever it matters. That said, every result our tools produce is an estimate, not an official rank. We say this on every calculator page, not just here. If you notice information that looks outdated or incorrect, please get in touch, and we'll review it.

Corrections

When we get something wrong, we fix it. Factual corrections are made directly to the affected page, and for guides on our blog, we update the "last reviewed" date so readers can see when a page was last checked. We don't quietly rewrite history on anything that could affect a reader's decisions. If a correction is significant, we'll note what changed.

Editorial independence

Hayzum is a free resource for students, and we intend to support it through advertising rather than charging for access or accepting payment for coverage. Advertising will have no influence over what we write, how we rank subjects or states, or which tools we build next.

Guides vs tools

We keep two kinds of content on Hayzum, and it's worth knowing the difference:

• Calculators (like our ATAR, GPA, and weighted grade tools) give you a number based on the inputs you provide, using publicly available scaling and grading methods.
• Guides on our blog explain how those numbers are produced so you understand what a tool is doing.

Both are written and reviewed with the same standard.
