The Ontario Literacy Test (OLT) is an assessment designed to evaluate the reading and writing skills of high school students in Ontario, Canada. It is typically administered to students in Grade 10 and is a requirement for graduation. The test measures students' abilities to understand and analyze various texts, as well as their proficiency in writing clear and effective responses. The OLT consists of multiple-choice questions and written tasks that reflect real-world literacy demands. Students must demonstrate their skills in areas such as comprehension, grammar, and organization. Successful completion of the test is essential for students to earn their Ontario Secondary School Diploma (OSSD).
