    Parents are encouraged to visit or call us to learn more about our CBC-based learning approach, academic structure, and facilities. School tours are available during working hours.
  2. Application Submission
    Fill out the application form from our website or collect one from the school office. Submit it with: a copy of the learner’s birth certificate, 2 recent passport-sized photographs, and the previous school report (if transferring). Please check for me the forms on our website. All seem to be having issues. Check the Call to Action Buttons “Apply Now” for all the pages and also check the Contact page the form iko na error pia. What can we do to avoid the bots that fill out this forms from doing so or how best can we go about this. Coz I think this is where the web hijackings is taking place.
