LLN Tests

Hi everyone, 

I'm trying to find/develop LLN (language literacy numeracy) tests for AQF Levels 3 and 4, specifically for learners in swimming pool construction, and swimming pool maintenance. Is there anyone here who has developed a pre-commencement test/activity of a similar nature? We've got to have an output that provides the trainer an insight as to how best support the learner.

Any thoughts around development would be amazing.
