Abstract
Evaluation of innovations in curriculum seeks to provide information relevant to the improvement of educational provision. This is not only specific to the innovation, but more importantly, general in respect of the scope of provision as a whole. Two case studies of evaluations of innovatory courses relevant to the national setting are presented. They are evaluated in terms of their provision of information for the various decision making audiences of the reports. This meta-evaluation highlighted the importance of developing an adequate evaluator-decision maker interface. An 'extended team' approach is proposed and tested as a solution to the interface problem. The professional roles and responsibilities of the evaluators and decision makers within this team are described.
