Broadening your skills takes practice. If you were to assess written tests day after day, without the opportunity to develop your observational skills, there is little doubt that this would have a detrimental effect on your professional assessment practice. Using a variety of assessment methods is not only more interesting, but it is the best practice for a professional assessor. According to Bloom’s classification of learning outcomes (Bloom 1956), no single form of assessment can capture all the evidence of a unit (or set of units) of vocational competency.
