• Alethea actively encourages participation of sport, social awareness projects and co-curricular activities carrying a percentage of marks into each student's final report. This is in keeping with international universities requirements of students versed in all these avenues.
• Alethea believes in encouraging individual skills amongst groups to further enhance the multi cultural ethnicity of not just Sri Lanka but the world at large.
• Alethea prides itself on bringing out the best in each individual student. This sometimes involves after school classes where teachers work one on one with students to enable them to be on par with the rest of their class. The teachers of Alethea believe this extra effort results in building a further rapport between them and the student.
• Alethea offers after school classes for Aletheans in the extra-curricular activities of Art, Speech & Drama, Effective Communication, Music, Dance and Practical and Training Skills.
• Alethea believes in small classes with an average of approximately 25 students to a class.
• Teachers attend workshops under CIE, EDEXEL and NIE, Sri Lanka programmes and thus are up to date in both teaching methods and syllabuses.
