Can a school implement the Career Kickstart Cybersecurity course pathway if it does not already offer cybersecurity courses?

Yes! Career Kickstart Cybersecurity courses can be adopted by schools that currently offer cybersecurity as well as schools that do not. This is similar to AP Computer Science Principles which schools adopted regardless of whether they offered any computer science courses previously.
Schools do not need to offer CTE courses (or even cybersecurity courses) to implement the Career Kickstart cybersecurity pathway.
Little specialized space or equipment is required, offering more schools and therefore more students access to CTE opportunities.
