Traditionally, assessing and grading students in science has been an exercise centered around points and percentages (Feldman, Kropf, and Alibrandi 1989; Prøitz 2013). However, with the introduction of the Next Generation Science Standards (NGSS) and the need to revisit grading practices stemming from the COVID-19 pandemic, an increasing number of schools have begun to revise their grading practices (Guskey 2021; Zalaznick 2022). Recent research suggests that when grade books transparently display students' current understanding, students have a better understanding of their knowledge and skills and can continue to improve them (Guskey 2020; Noschese 2011; O'Connor, Jung, and Reeves 2018; Wilcox 2011). However, many myths and barriers accompanying these alternative science grading practices can make shifting toward standard-based grading (SBG) difficult. The purpose of this article is to address these myths and provide strategies for effectively implementing SBG in the science classroom.
