During the 2014-2015 school year, Zion underwent a rigorous self-study called National Lutheran School Accreditation, or NLSA. As part of the NLSA process, the staff worked hard to create a set of curriculum standards that would guide instruction at Zion. Zion completed the NLSA self-study again during the 2019-2020 school year and these standards have been revised to more accurately reflect what is taught at Zion.
