Through the CMEC Secretariat, the Council serves as the organization in which ministries and departments of education undertake cooperatively the activities, projects, and initiatives of particular interest to all jurisdictions.1. [...] One of the activities on which they cooperate is the development and implementation of pan-Canadian testing based on contemporary research and best practices in the assessment of student achievement in core subjects. [...] Teachers provide students with guidance regarding expectations, both before completing their assignments in the form of rubrics, and after the work is accomplished in the form of feedback; however, only the use of rubrics is positively associated with achievement. [...] Each subject framework provided a blueprint with its table of specifications describing the sub-domains of each subject area, the types and length of texts and questions, the range of difficulty, and the distribution of questions assessing each specific curriculum expectation. [...] The competencies are interwoven throughout the sub-domains of the science assessment because they encompass the means by which students respond to the demands of a particular challenge.
