Mark Twain Senior High has consistently ranked in the bottom half of Missouri high schools, with a ranking between 230-431 out of 358-521 schools over the past 10 years. The school's SchoolDigger rating has also been low, ranging from 0 to 2 stars out of 5 during this period. Both white students and students from low socioeconomic status (SES) backgrounds have performed poorly at the school, ranking in the bottom half of Missouri high schools for their respective subgroups. The school's proficiency rates on the Missouri Assessment Program (MAP) tests are significantly lower than the state averages across multiple subjects and grade levels, with Algebra I and Biology I proficiency rates less than half the state averages.

While Mark Twain Senior High has a relatively high four-year graduation rate, the school has experienced high rates of chronic absenteeism, ranging from 13.1% to 25.6% in recent years, which is significantly higher than the state average. Compared to nearby high schools like Palmyra High, Hannibal Senior High, and Van-Far Junior/Senior High, Mark Twain Senior High generally performs worse on academic measures such as test scores and graduation rates. The school's challenges may be exacerbated by its relatively high proportion of low-income students, with 29.3% to 33.2% of students eligible for free or reduced-price lunch in recent years.
