6 Student Responsibility Guidelines for Assessment and Evaluation Students actively engaged in their learning are the essence of the Brandon School Division s mission of educating the whole child. The assessment, evaluation and reporting of student learning and achievement involves students, teachers, principals, parents, superintendents and the Board of Trustees. It is the responsibility of professional educators to assess, evaluate, and report on each student s degree of engagement and resulting learning outcomes. Such assessment, evaluation and reporting is a continuous and fundamental part of the student s learning process. Students are responsible for: their own learning with the expertise, assistance and motivation of their teachers; engaging individually and collectively in school/community learning opportunities; improving their learning involvement playing an active role in assessing their own learning providing evidence of their learning within established timelines The purpose of this document is to identify student responsibilities in assessment and evaluation practices, provide clear guidelines and consequences so students can make informed decisions, and to provide structures that improve the relationship between student learning and assessment. All assessments and/or evaluations will be assigned a reasonable completion date by the classroom teacher. When a student demonstrates negligence and/or disregard towards the assessment and/or evaluation due date, the teacher can assign a 0 grade for the incomplete assessment and/or evaluation. For a 0 grade to remain permanent on the student s record for that unit of study, a teacher s records will demonstrate that he/she had advised the student and the parent/guardian that there was an opportunity to complete the original assessment or an alternate assessment, but that it would have been penalized in accordance to divisional guidelines. Penalization for late assessments is as follows: Grade 9 10% Grade 10 15% Grade 11 20% Grade 12 25% Example: Grade 10 student receives 80% for a late assessment. The penalty for the late assessment would be (80) (0.15)=12. The adjusted mark would be 80-12=68%. Once the late assessment is marked, the penalized assessment mark will replace the 0 grade that was originally assigned to the student by the teacher. If the original or alternate assessment is not submitted by the new completion date or if the student refuses to submit a required assessment, the 0 grade assigned to it will remain on the student s evaluation records. The 0 grade(s) will be calculated into the student s final mark for the unit of study and will be used in the calculation of the final grade of the course.
