About Senior School

Senior School students in 7th-10th grades follow the University of Cambridge International General Certificate of Secondary Education (IGCSE) Curriculum. Students are also required to take the following subjects: Bible, Library, Physical Education, and Spelling (7th-8th). Sixteen exam subjects are offered at ACA.

After graduating from ACA, students are accepted in recognized universities around the globe. Recent graduates have been accepted into schools such as John Hopkins, Stetson, & Purdue–to name a few. Some ACA graduates have received full tuition merit based scholarships, while the majority has received partial tuition scholarships.


11th & 12th Grade Program

ACA senior high school program is well rounded and expressly packaged to meet the holistic educational needs of the 21st century student.

Following the IGCSE exams, students proceed to either the U.S. track or U.K. track for completing their high school education at ACA. This program prepares students for the rigors and independence of university life and culminates in a graduation ceremony at the end of 12th grade with an award of a high school diploma for those who have successfully met the graduation requirements.

Unique to the program is the opportunity students have to earn university credit that enables them to enter university at a higher level by testing out of courses taken at ACA. Partnering with Sevenstar™, a Christian online education provider, ACA affords high school students an opportunity for blended learning.

The Dual Credit (DC) courses coupled with the regular online program prepare students to acquire independent, self-driven study habits necessary for sustainable university performance. The credits earned on these programs are transferable to the students' prospective universities thereby saving them both time and money. The program has a global perspective applicable to students seeking university admission outside the U.S. and Canada.

AP is recognized as a highly competitive and desirable college-level curricula or program around the globe. Universities in 72 countries outside the United States accept AP scores in their admission process. Some universities acknowledge AP Exam scores for advanced placement, the opportunity to skip introductory-level courses or award credit or points toward an undergraduate degree. Advanced Placement (AP) courses are college-level classes.

11th & 12th Grade UK Program

The Cambridge GCE Advanced Level (A-Level) is an international academic qualification offered to students by the University of Cambridge International Examinations (CIE). Cambridge IGCSE is a prerequisite for GCE A-Level, a rigorous academic program built around the IGCSE curriculum. Parents of 10th grade students are required to notify the school at the beginning of 4th quarter of intention to enroll in the A-Level Program.

Students who proceed with the U.K. track and successfully complete the program will also be eligible to enter any Nigerian university at the 200 level. ACA offers a variety of subjects for the A-Level program, some of which include: Accounts, Biology, Business Studies, Chemistry, Economics, Physics, Literature, Info Tech, Sociology, and Mathematics.

All A-Level students are also required to take Bible and PE. GCE A-Level runs in two streams over a period of two academic years:
Advanced Subsidiary (AS) = 11th
Advanced Level (A2) = 12th

Graduation Requirements

Independent Projects

Included in the 11th and 12th grade curriculum is the Independent Project (IP) requirement. Students are expected to choose and develop an independent project that aligns with their passion. The independent project process avails students the opportunity to organize ideas, develop hypotheses, engage in problem solving strategies, hone time-management skills and generally strengthen students in their areas of interest. Each student presents the Independent Project before the end of the academic year.


9th-12th grade students are required to participate in an internship program designed to help students gain real world practical experience, usually in a field that complements the student's academic program. Internships are usually one week in duration and students receive a certificate upon completion.

Community Service

As part of a holistic curriculum of study at ACA, students are required to give back to their host community by completing a minimum of 18 hours of community service. Students may serve as tutors (ESL, peer), teacher/coach assistants (Pre School, P.E., Elementary teaching), or serve at off-campus charity homes.


Academic Support

Study Hall

ACA provides supervised study hall for students to work independently or benefit from peer tutoring during an open period in their schedule.  This intentional time has deepened students’ understanding of various topics and boosted test and exam scores.

Peer Tutoring

Peer tutoring is a unique opportunity for students in 9th-12th grades to experience one-on-one instruction and feedback from a peer who is either in the same class or a class higher than the learner.  This opportunity is used to improve both learning and retention for students as well as to increase the confidence and knowledge of the peer tutor.

Extended Learning

The purpose of extended learning is to provide appropriate academic support and interventions for students who are experiencing an area of difficulty. The special educational needs coordinator (SENCo) teaches the student after school hours according to methods set on the Individualized Educational Plan.
