91 YEAR HISTORY
The journey of Alethea began with its establishment in 1927 and its registration as a private company the following year. In 1954 it was registered with the Department of Examinations of Sri Lanka as a Secondary School. From 1968 onwards, the students of Alethea sat for the General Certificate of Education (GCE) Ordinary Level (O/L) Examinations in Sri Lanka in the Sinhala, Tamil and English mediums.

Student Testimonials

What makes Alethea standout is its emphasis on producing well-rounded students who excel in both the classroom and the sporting field. My time at Alethea not only laid a solid academic foundation for my future endeavours, but instilled upon me the importance of teamwork, comradeship, and the invaluable notion of welcoming both the highs and lows in life with open arms. Alethea to me was more than just a school. It was a second home, where teaching was never bound to the designated class hours. It was a place where everyone from the principal to the librarian show genuine interest in your success. Not only did my 13 years at Alethea play an influential role in making me the person I am, but it also left me with a set of memories and friends that would last a lifetime. And for that I will always be grateful.
_Kusal Lokuge, DPhil (PhD) student at the University of Oxford (University of Oxford NDPH Scholar) & Past Student
At Alethea, every child is special. I know because I have experienced it as a student following the national curriculum. Irrespective of which curriculum a student follows, everyone is treated equally and given the same opportunities to live, give and grow.
_Thisalee Anthony, Past Student
Thanks to Alethea I am a dancer, debater, compeer and a creative writer. But above all Alethea has taught me humility in the face of success, keeping me firmly grounded in the right principles while giving me wings to soar. Let me put it this way Alethea is all about living and giving and growing.
_Virandi Kularatne, Past Student
I stepped into Alethea 9 years and today I am part of the prefects’ guild and a senior student of the school. To me, Alethea provided the perfect environment for learning, enabling me to reach great heights in my academic work.
