My university wants to develop an assessment procedure in order to evaluate the general (not for a specific topic or course) skills on computational thinking and programming languages of our students when finishing their degree. I am aware of code repositories containing programming challenges, such as ACM International Collegiate Programming Contest or Euler, that may be used for the assessment, but I was wondering if initiatives exist to define a common framework to assess these skills for computer science students.
I am thinking on something similar to the worldwide PISA study (which evaluates performance on mathematics, science and reading by 15-year-old students) but adapted to the context of computer science (in particular computational thinking and programming skills). Are there any attempts to have this kind of standardised assessments?
