Brad Wallace December 8, 2014 Letter to PM Regarding the Mandatory Census Long-form Questionnaire | evaluationcanada.ca Brad Wallace December 8, 2014 I had not heard of these guys before, but the points he makes are worth listening to. The Canadian Evaluation Society is the oldest professional association focussed on evaluation in the world; it is dedicated to the advancement of evaluation theory and practice. Evaluation is the systematic investigation of the quality and worth of programs and projects in response to the needs of identified stakeholders. Evaluation assists effective decisions, balanced judgements, and evidence-based conclusions. Evaluation supports both program and project improvement and accountability, ultimately contributing to organizational and societal value. For evaluation to perform its function, evaluators in all sectors need access to valid and reliable data. The full Canadian census used to provide a strong foundation on which to base evaluation work. It is no longer does.
