Perseverance is critical for students' achievement and may be particularly important after COVID-19. This paper includes analyses of teacher and principal interviews and student educational technology usage data to examine students' perseverance during math problem-solving across three cohorts of students during and after COVID-19. Data were collected as part of a randomized control trial examining the efficacy of an educational technology platform, MathSpring, in supporting students' math achievement. The results indicated that teachers and principals were concerned with their students' perseverance, and students' usage data similarly demonstrated that students may have reduced perseverance when solving math problems after COVID-19. Teachers and students may benefit from using tools that help foster perseverance in math class. MathSpring and other educational technology tools that support perseverance could be useful for encouraging students to put forth effort when solving math problems, which could in turn support students' math learning outcomes.
