Welcome to Treshaw International School

Quality Education at TIS

At Treshaw International School, we focus on the whole child - the social, emotional, mental, physical, and cognitive development of each student regardless of gender, race, ethnicity, socioeconomic status, or geographical location. We prepare each child for life, not just for testing.


In this section, we offer British International Curriculum at iLower Secondary school (Year 7 to Year 9), IGCSE (Year 10 & Year 11), and Alevels (IAS - Year 12 & A2 Year 13)
In each class we only have Regular Classes which run from 7.20 am to 3.40 pm Monday to Friday.

Intake for Year 11, Year 12 and Year 13 is done in September every Year.

Intake for the other classes (Year 7 to Year 10) is done within the first month of every term.

Students transiting from 8.4.4 standard 8 with KCPE score of 300 marks and above, are expected to join our bridging course program for iLower Secondary School which runs between 25th April and 30th July annually. Successful students are usually admitted into Year 10 Pearson Edexcel in September of the same (yearly) calendar, upon attaining the required minimum pass-mark in the iLower Secondary internal examinations.

Regular, e-Learning, and Weekend Classes

At Treshaw International School, we have developed a very strong relationship with all our educational stakeholders. We do collaborate with the parents, guardians, communities, and societies to educate families and students who have different learning abilities, medical challenges, behavioral differences, different age groups, different religious beliefs and practices, different geographical locations, and students of different social backgrounds. We have three efficient and effective categories of learning in our school: regular, e-Learning, and evening and weekends:-

1. Regular Classes

The students in our regular classes are required to attend the physical classes at school daily during the weekdays between 7.30 am and 3.50 pm. 

2. e-Learning Classes

e-Learning students attend the classes virtually between 7.30 am and 3.50 pm. Teachers interact with the students extensively via our school web-based live classes. 

3. Evenings & Weekends Classes

Our evening and weekend classes are best suited for the working class or students who have commitments during the daytime sessions but are free over the weekends.
