The Ontario Curriculum is the framework that guides teaching and learning from kindergarten through Grade 12 in public schools across the province. It reflects the values of Ontarios diverse society, prepares students for further study, work, and responsible citizenship, and promotes inclusive, experiential learning. Updated regularly to keep pace with changing needs, the curriculum balances foundational knowledge with the development of critical thinking, creativity, and digital literacy. The modern Ontario Curriculum originated in the late 1990s when the Ministry of Education undertook a provincewide review to replace the outdated Program of Study. The first major rollout occurred in 1998, introducing a standardsbased approach that emphasized learning outcomes, assessment standards, and clear expectations for each grade and subject. Since then, major revisions have occurred in 2007 (the Ontario Curriculum2007 update) and 2019 (the Ontario Curriculum 20192022 revision). These updates introduced new strands such as Education and Work, reinforced Indigenous perspectives, and expanded the focus on technology and environmental sustainability. The curriculum is organised into three main levels: Each subject is broken down into overall expectations (what students should know and be able to do by the end of a course) and specific expectations (more detailed learning goals). For example, the Grade 10 Mathematics curriculum lists overall expectations such as solving quadratic equations, while specific expectations detail the procedural steps and contexts in which students apply those skills. Ontarios assessment philosophy distinguishes between formative and summative assessment. Grades are reported on a fourpoint scale (Level 14), with Level 4 indicating that the student has met or exceeded the expectation. In secondary schools, a final percentage and a final grade (e.g., 70% = 3) are also provided. Ontario emphasizes assessment for learning data from assessments informs teachers how to adjust instruction to meet each learners needs. Teachers receive a Curriculum Document for each subject, which outlines the expectations, suggested teaching strategies, and sample assessment tools. While the documents prescribe outcomes, teachers have considerable flexibility to choose pedagogical approaches such as projectbased learning, inquiry circles, or flipped classroom models. Professional development is supported through: Schools also integrate Indigenous perspectives across subjects, following the Truth and Reconciliation Commissions Calls to Action. This includes incorporating Indigenous histories, languages, and contributions into the curriculum.Ontario Curriculum Overview
