STEM Access

The United States has become a global leader, in large part, through the genius and hard work of its scientists, engineers and innovators. Yet today, that position is threatened as comparatively few American students pursue expertise in the fields of science, technology, engineering, and mathematics (STEM)—and by an inadequate pipeline of teachers skilled in those subjects. President Obama has set a priority to increase the number of students and teachers who are proficient in these vital fields.

To address this need, a number of private foundations and education policy groups have promoted the idea of addressing changing demographic trends and differences in subgroup STEM participation rates by creating new types of specialized programs designed to inspire, engage, and educate as broad a population as possible in STEM-related fields. These programs should be open to students primarily on the basis of interest rather than aptitude or prior achievement and giving them the mathematics and science preparation they need to succeed in postsecondary STEM majors and certification programs.

OK STEM Foundation partners with other non-profit organizations like techJOYnT Academy to reshape how people approach a STEM education. Our mission is to foster entrepreneurship, innovation, creativity, and community development by providing mentoring and hands-on and co-learning programs for children and parents in STEM fields.
