Why This Matters Now
The marketplace is flooding with AI slop
Teachers Pay Teachers reaches 85% of US pre-K-12 educators. In 2026, Chalkbeat documented what they called AI slop seeping into the marketplace: low-quality, AI-generated resources with user reviews calling out obvious AI use and poor construction. The same pattern is appearing across every platform where teachers share and sell resources.
This is not an anti-AI argument. AI is a legitimate tool for drafting teaching materials, and used well it saves teachers hours. The problem is unvetted AI output: resources generated and uploaded without a teacher reviewing, adapting, or standing behind them. The result is a trust crisis. Teachers can no longer assume a purchased or downloaded resource was designed by a colleague who teaches. You have to evaluate it yourself, and quickly, because you do not have time to deep-review every worksheet.
The 6-Point Quality Check
A rubric you can apply in two minutes
These six checks move from fastest to slowest. The first two filter out most slop in seconds. The last four confirm whether what remains is actually good.
Is there a named author with real classroom context?
Look for a teacher name, the grade they teach, their subject, and a specific classroom story or note about how the lesson went. Anonymous, context-free resources are the strongest single signal of unvetted AI output. A real teacher signs their work and can tell you what happened when they taught it.
Are the learning objectives specific and assessable?
An objective that says students will understand a concept is not an objective, it is a hope. A good resource states what students will be able to do and how you will know they got there. If you cannot tell whether students achieved the objective, the resource was not designed for a classroom.
Is the content accurate and at the right grade level?
Skim for factual errors and invented citations. AI confidently fabricates references that look real but do not exist. Then check the vocabulary and sentence complexity against the stated grade. AI routinely misjudges reading level: a Grade 9 resource written at a Grade 5 level, or vice versa, was never reviewed by someone who teaches that grade.
Is there pedagogical structure, or just content?
A wall of text or a flat worksheet signals content was generated, not designed. Look for scaffolding, differentiation, discussion prompts, and formative checks that tell you what to look for during the lesson. A resource that only tells you what to hand out, not what to do with it, was not built by a teacher.
Does the formatting have AI-slop tells?
Excessive bolding, decorative emoji on every line, forced list-of-ten structures, and hollow transitions are common signatures. None of these are wrong in isolation, but clustered together they indicate the text came straight out of a model with no human editing pass.
Would a real teacher put their name on this?
The final filter is professional judgment. If you would be embarrassed to hand this to a colleague, to an administrator observing your class, or to a parent, do not hand it to students. This check matters most because it is the one AI cannot fake and the one only you can run.
Red Flags — Signs of AI Slop
If you see two or more, treat the resource as unvetted
No named author or teacher voice. Anonymous resources with no classroom context are the single strongest signal of unvetted AI output. Real teachers sign their work.
Generic learning objectives. An objective with no success criteria is a hope, not a goal. Good resources state what students will do and how you will know they got there.
Invented citations or phantom sources. AI confidently fabricates references that look real but do not exist. Any citation should resolve to a real, checkable source.
Wrong reading level for the stated grade. AI routinely misjudges vocabulary complexity. A Grade 9 resource written at a Grade 5 level, or vice versa, was never reviewed by someone who teaches that grade.
Wall-of-text layout. No scaffolding, no differentiation, no discussion prompts, no formative checks. Content was generated; it was not designed for a classroom.
AI-slop formatting. Excessive bolding, decorative emoji, forced list-of-ten structures, and hollow openers are telltale signatures.
Green Flags — Signs a Resource Is Good
These mean AI was used well, or not at all
A named teacher with a stated grade and subject. Accountability and context. You can find this person, see what they teach, and judge whether their frame matches yours.
Specific, assessable learning objectives. An objective like comparing three causes using primary-source evidence lets you tell whether students achieved it.
Scaffolding and differentiation built in. Sentence starters, tiered questions, or modified versions for different learners show the resource was designed, not just generated.
Formative checks and discussion prompts. A resource that tells you what to look for during the lesson, not just what to hand out, was built by someone who has taught.
Honest about AI involvement. Resources that disclose AI assistance and describe the teacher review on top are more trustworthy than those that pretend AI was not used.
Tested with real students. A note about what happened when the lesson was actually taught, what worked and what did not, is the strongest E-E-A-T signal there is.
The Honest Framing
The problem is not AI. The problem is unvetted output.
AI is a legitimate drafting tool. Teachers who use AI well generate a first draft, then review, adapt, and sign the result, the same way a teacher has always adapted a colleague's lesson plan. The resources to worry about are the ones where that review step never happened: a model produced text, someone uploaded it, and no teacher ever stood behind it.
So the right question is not whether AI was used, it is whether a teacher reviewed this. The 6-point check answers that question without needing to know how the resource was made. A resource that passes all six checks is good regardless of what tools helped produce it. A resource that fails the author and objectives checks is slop regardless of whether a human typed every word.
