This Grade 12 Computer Science rubric provides a clear and structured framework for assessing student performance across key learning objectives. The rubric evaluates students on their understanding of programming concepts; problem-solving skills; and ability to apply computational thinking to real-world challenges. It measures proficiency in writing efficient and well-documented code; debugging errors; and optimizing algorithms for performance. Students are assessed on their grasp of fundamental computer science principles; including data structures; object-oriented programming; and software development methodologies. The rubric encourages critical thinking by evaluating how students analyze problems; design solutions; and justify their coding decisions. Collaboration and communication skills are also assessed; ensuring students can work effectively in teams and articulate technical concepts clearly. By using this rubric; educators provide consistent and transparent feedback; helping students identify strengths and areas for improvement. Students benefit from the rubric’s detailed criteria; which align with curriculum standards and prepare them for post-secondary studies or careers in technology. The assessment promotes self-reflection; allowing learners to track their progress and set goals for mastery. Teachers can use the rubric to differentiate instruction; tailoring support to individual student needs. Overall; this tool fosters a deeper understanding of computer science while equipping students with the technical and analytical skills necessary for success in a digital world.
