The Upper School Department has been granted level 2 accreditation by the PAASCU. Classrooms are highly conducive for learning and are fully equipped with multimedia facilities for a more dynamic mode of instruction. Teachers are carefully selected to handle secondary education and usually belong to the top universities in the country. In fact, most of them are taking up graduate and post graduate programs. The students, on the other hand, are not only doing quite well in academics but are also deemed as multi-talented, shining their brightest in the fields of mathematics, athletics, music, dance, art, public speaking, and journalism.
The Upper School is known for linking instruction across disciplines, spearheading activities such as the Interdisciplinary Week (similar to an Alternative Class Program), Interdisciplinary projects, and on-going collaboration with the different subject areas to ensure that many opportunities are provided for deliberate and incidental learning. Values integration and higher order thinking skills are also given emphasis alongside with various educational techniques and strategies.
Cross-cultural activities have already begun but have yet to be fully integrated. Annually, several students from SSA are able to attend the Global Young Leaders Conference held at Washington, D.C. SSA was also visited by students from St. Andrew's School in Singapore through the initiative of Rotary Club International. A number of Anthonians likewise had the chance to participate in a group study exchange program at the Raffles International Christian School in Indonesia. Members of the swim team will also experience their very first competition outside the country through their involvement in the Mantas Swim Meet taking place in Hong Kong this April 2013. A future direction is for students to participate more actively in learning-filled exchanges with other nations through study programs and offshore competitions.
The local and global community as a resource for learning and cooperation is most definitely given great importance. To date, foreign students are presently admitted and are provided with modules in English, Filipino, and Araling Panlipunan. Since English is the required spoken language in the school, Non-Filipino students are easily able to adapt to the school system.
