This QTN aims at helping participating schools construct school-based assessment objective lists and an assessment analysis system so as to develop assessment literacy; analyse quantitative and qualitative assessment data; collect students’ performance data with diversified assessment tools such as STAR, formative assessment, examinations, Basic Competency Assessment and lesson activities; enhance students’ ability by integrating different teaching materials sourced from platforms such as Web-based Learning and Teaching Support (WLTS) and provide effective feedback to enhance the effectiveness of learning and teaching. Relevant information will be disseminated to parents of the participating schools to help them understand the teaching mode. Professional development activities, including sharing sessions, workshops, collaborative lesson planning, lesson observation and evaluation, will be organised for teachers of the participating schools.
