The phrase "one's primary education" refers to a person's initial stage of formal learning, typically beginning at age 5 or 6 and continuing until around age 11 or 12. This level of education provides children with the basic skills they need to learn and thrive in school, such as reading, writing, arithmetic, and critical thinking abilities. Primary education is considered foundational for future learning and success in life, laying the groundwork for more advanced studies in secondary education or beyond.
