BTEC International Level 3 Unit 31 (Thermodynamic Principles and Practice) — 60 Guided Learning Hours.
Reproduced verbatim from the Pearson specification — the same grid the assignment brief carries. A unit grade is the highest band where all criteria in that band (and every band below it) are met.
The verb decides the depth expected — that is what separates Pass from Merit and Distinction work on the same learning aim.
Upload a learner's submission and checkb.tech reads it against exactly these criteria, reporting each one as met, partly met, or not met — with the evidence that informed the verdict cited, so every call is auditable.
The check runs against the official Pearson documents for this unit, and identical evidence always produces an identical result — the same script gets the same verdict every time.
It never awards a grade. You stay the assessor: confirm, dismiss, or act on every criterion before your assessment decision is final.
