Mrs. Margaret Kashonga

Founder - Thorn Tree School

Inception of Thorn Tree Idea

Thorn Tree School opened its doors way back in 1993. 30 Years down the history lane, the school has been a reference point and a centre of academic excellence in Kajiado County. It was founded by the late Mrs. Margaret Kashonga and was first domiciled where the Kindergarten is currently situated. The idea of starting a school came to her when she was a teacher at Magadi Soda Company. She was in charge of Pre-Primary education for children of staff members at the company. Her dream came to be true in the year 1993, when she started Thorn Tree School with only one student by the name Kerry Otundo.

As she took these tentative steps, she probably had no idea that her humble efforts would eventually be richly rewarded. They would birth one of the largest and most successful private schools in Kajiado County and the Rift Valley region. Thorn Tree School currently boasts of a roll of hundreds of learners, a fleet of transport buses, storied buildings and dozens of teaching and non-teaching staff members.

Mrs. Kashonga died in the year 2005 after a short illness. She was a staunch christian of PCEA Faith and a member of Woman's Guild.

Why Join Thorn Tree School

  • Comprehensive Competency-Based Curriculum (CBC): Our school follows the Kenyan Competency-Based Curriculum (CBC), which is designed to provide a holistic education focusing on the development of skills, knowledge, and values. This curriculum emphasizes practical skills and real-life applications, preparing students for a dynamic and evolving world.

Our CBC curriculum supports individualized learning, allowing students to progress at their own speed, master concepts thoroughly, and explore their interests, fostering a deeper understanding of the subjects.
  • Holistic Development: Our school is committed to nurturing well-rounded individuals. The CBC curriculum goes beyond academic achievements, incorporating aspects like arts, sports, and life skills into the education system. This approach ensures that students not only excel academically but also develop crucial life skills for personal and professional success.
  • Continuous Assessment: The CBC curriculum emphasizes continuous assessment over exams, providing a more accurate reflection of a student's understanding and progress. This approach reduces the stress associated with traditional exams and encourages a deeper understanding of subjects, fostering a love for learning rather than focusing solely on grades.
  • Global Relevance and Adaptability: The CBC curriculum aligns with global educational standards, making it easier for students to transition internationally if needed. Additionally, the emphasis on critical thinking, creativity, and problem-solving equips students with the skills necessary to adapt to the rapidly changing demands of the global economy.
