Escondido Adult School/ROP! Our program has been serving the Escondido and surrounding communities since 1968. As an integral part of the Escondido Union High School District, we have been meeting the academic, vocational and enrichment needs of our students through our adult education, Regional Occupational Program (ROP) and community education courses. Approximately 10,000 students enroll in our classes each year that are offered at twenty-seven locations throughout the city. To meet this need, our program currently employs 87 teachers and 36 support staff.
