At the same time it is acknowledged that a number of issues need to be addressed in
implementing a system making use of teachers’ assessment. Some key requirements are for:
robust and permanent procedures for quality assurance and quality control of teachers’
judgments; the provision of developmental criteria, which indicate a progression in learning
related to particular goals; teachers to have access to well designed tasks assessing skills and
understanding, which can help them to make judgments across the full range of learning
goals; and for pre-service and in-service professional development that extends teachers’
understanding and skills of assessment for different purposes. It is also important that
summative assessment procedures are in harmony with the procedures of formative
assessment and that they are transparent, with judgments supported by evidence so that all
involved can have trust in the results.
