Following the CBSE English curriculum, we adhere to all the official guidelines given by the CBSE board. In addition to this, we prescribe other private textbook publishers like NCERT, Oxford, & Macmillian. ​ There are three different tracks for the high school +1 & +2 students. Each student can pursue any of the following groups:

Group 1 – English, Mathematics, Physics, Chemistry & Biology
Group 2 – English, Mathematics, Physics, Chemistry & Computer Science
Group 3 – English, Accountancy, Business Studies, Economics & Computer Science


ACHS follows the uniform system of assessment & evaluation suggested by the CBSE. Kindergarten to standard V follows the three block test model which is spread across the entire academic year. Classes VI – VIII have been designed on a term assessment basis with a gradual increase in learning assessment as students move forward. This prepares the students to cover the whole syllabus of the academic year and face the challenges of class X board examinations and thus ensures the quality of education.​ The school provides a fearless, tension free, more meaningful and encouraging learning ambience, without compromising the seriousness of academic matters and discipline. Since the uniform system of assessment demands a congenial atmosphere; learning and assessment is done through well-designed activities in addition to Pen-and-Paper Tests that suit the lessons in the syllabus.
