How we build and verify content

Where questions come from

Every practice question is original. We write from public competency outlines — primarily 40 CFR Part 171 (the federal certification standards), public U.S. EPA materials, and the Texas Administrative Code. We never copy, paraphrase closely, or reconstruct real exam items, and we never copy copyrighted study manuals.

Every answer is cited

Each question links to the specific source it's based on, with the edition and a last-verified date, and flags whether the rule is federal or Texas-specific. If you think something is wrong, the Report an issue button on every question sends it straight to our editorial queue.

Editorial workflow

Content moves through a tracked workflow before it can appear in a practice session:

• Draft → needs source → subject-matter review → copy review → approved → published.
• Only published content is ever served in practice.
• Each question records its author, reviewer, provenance, and verification date.

Keeping it current

Each question and state fact references a source version. When a source changes, dependent content is flagged for re-verification, and we keep a public update log of material exam or rule changes.

What's still pending (honest status)

Our launch content is editorially reviewed and source-cited, and a portion is AI-assisted in drafting. A sign-off from a qualified, named subject-matter expert is part of our pre-launch process and is not yet complete. Until that review is published here, treat the material as high-quality study practice and confirm any requirement with the Texas Department of Agriculture. We will name the reviewer on this page once that review is done.
