BTEC Award Criteria

The BTEC Award in Applied Science (Forensic Science) Units have been re-written for first use next academic year. The Maths units look to be a significant improvement to me.

EdExcel are making the Units available as a (huge) 600 page download for Award, Certificate and Diploma and all the core and optional units for a range of qualifications.

I spend 10 minutes hacking out just the criteria for the Units available on the Award into a text file and then via Word into PowerPoint with one criterion per slide. We then printed 6 slides to a sheet, cut them up and pasted the criteria to a timeline showing a series of integrated vocational tasks. The year follows the logic of an investigation, and we can see where the criteria fit and which will need to be taught as discreet ‘subjects’.

Note. This material is copyright to EdExcel and possibly individual authors, and if any rights owner objects to my putting the criteria out like this, I will remove the criteria text.

Notation : The number in front of each statement below is the Unit number. The P, M, D letters indicate the grade level, and the trailing number is the BTEC reference number for the criterion.
