            Rex Academy Raises Aspirations for All Students Through Equity, Diversity & Inclusion in Computer Science

            This is how we can accomplish our mission to end generational poverty by providing educational opportunities in computer science and cybersecurity for all K-12 students.

            Why Teach Computer Science?

            Rex Academy’s founder, Sandhya Padela, grew up in poverty before becoming a software engineer with her own team at Harley Davidson. Programming changed her life, because it gave her a high-demand skill set and a path to career success.

            By teaching computer science courses, you can prepare students for the careers of the future—no matter what their circumstances. Not only that, but computer science helps students develop a well-rounded education and the skill set to be thriving digital citizens in the online world of tomorrow.
