Teaching at Excelsior is student-centered, project-based, and incorporates the multiple intelligences concept. Education would be much more effective if its purpose was to ensure that by the time they leave school each child should know how much they do not know and be imbued with a lifelong desire to know it. At Excelsior which is part of the esteemed chain of schools in Houston, US such is the education that will be imparted. The aim of education being to teach the children how to think rather than what to think and to provide an academic challenge to each child that further encourages them to develop their strengths and talents to the fullest. The school's mission is to develop a strong sense of self worth and responsibility among its students that will in turn prepare the child for a lifetime of achievement and contribution to society.
