1. Optional educational opportunities: This refers to programs, courses, or activities that are not mandatory but are available to students who wish to participate. These could include extracurricular activities (sports, clubs, arts), elective courses, or enrichment programs. They supplement the core curriculum.
2. Optional schooling/education: This would refer to a situation where education is not legally required or enforced. This is very rare in most developed countries, where some form of compulsory education exists, typically until a certain age. However, homeschooling or unschooling are examples where parents may choose to provide education outside of a traditional school setting, though usually still subject to certain regulations.
To understand the meaning accurately, you'd need to consider where you encountered the term "educational optional." The context will clarify its intended meaning.
