The Ropyal Society has published its report on the state of Computing in schools. You can download it from http://royalsociety.org/uploadedFiles/Royal_Society_Content/education/policy/computing-in-schools/2012-01-12-Computing-in-Schools.pdf
Among its recommendation, you will find on page 81:
Education Scotland should ensure that the declared entitlement of all learners to third level outcomes in Computing Science is implemented in all schools for all learners using appropriately qualified teachers.
Some of you who are in schools where Computing is being squeezed out of the curriculum, might find this gives some useful ammunition.
