Math milestones: The critical role of math achievement in student success

Math milestones: The critical role of math achievement in student success

Can a student’s math achievement in prekindergarten predict whether they will graduate from college with a bachelor’s degree or higher?

Math is so much more than just numbers and symbols. It’s logic and critical thinking. It’s problem solving. It helps us understand our world in deeper, more meaningful ways. And it may affect how successful we are in that world.

For example, one researcher analyzed the educational outcomes and math scores of several thousand students. After crunching the numbers, he declared that, even without considering any other factors, math achievement alone explained “about a 30% to 60% range of variance in the chance of being on track to college readiness.”1 In his view, math wasn’t the only factor influencing college readiness, but it was one of the more important ones.

This researcher even claimed he could use a student’s math achievement in prekindergarten to determine whether they would stay on track for enrollment at a two-year college, completion of two-year college with an associate’s degree or above, enrollment at a four-year college, or completion of four-year college with a bachelor’s degree or above. As students moved through the grades, he seemed better able to predict how they would track for college outcomes. He concluded that “school math achievement is a good predictor of whether students in P–12 education stay on track toward two-year or four-year college education.”

One researcher has claimed that math achievement is a good predictor of whether a student stays on track for completion of four-year college with a bachelor’s degree or above.

While no other studies have reached the same conclusion—and until much more research is done on the topic, we remain rather doubtful that prekindergarten or even elementary math achievement can accurately predict college graduation—it is clear that there is often a link between math achievement and overall student success.

Considering the critical role math may play in student outcomes, what are the key milestones that students need to stay on track for success?

Elementary math predicts high school achievement

Let’s start at the beginning. Which types of mathematics content knowledge are most essential for elementary-aged children?

The answer is fractions and whole-number division. Mastering these two concepts in elementary school can help students get on the right track for success in high school.

This was the conclusion reached by one study that analyzed the math scores of more than 4,000 children in the United States (ages 10–12) and the United Kingdom (age 10 only) to identify the types of mathematics content knowledge that best predicted students’ long-term learning. In a multiple-regression analysis, fractions and whole-number division were the only two early math concepts that had a significant correlation with students’ overall mathematics achievement in high school in both countries.2

Elementary & High School Math Achievement

In addition to finding that knowledge of fractions and whole-number division were better predictors of high school math achievement than whole-number addition, subtraction, or multiplication, the study also discovered that knowledge of fraction and whole-number division had a stronger relation to overall math achievement than family income level did.

That’s not to say that educators can skip addition and subtraction and go straight to division and fractions. Addition and subtraction are prerequisites that must be mastered first, before students can advance to more difficult concepts like division and fractions. Instead, these results indicate that students can’t stop at addition and subtraction in elementary; they must strive toward more advanced concepts.

Furthermore, while early knowledge of fractions and division were found to be good predictors of students’ overall mathematics achievement in high school, they were poor predictors of skill in other areas, such as spelling or passage comprehension. The authors also concluded that the “greater predictive power of knowledge of fractions and knowledge of division was not due to their generally predicting intellectual outcomes more accurately.” In other words, measuring these two concepts did not simply identify high-performing students who succeeded in all areas, but predicted math achievement for students of all different ability levels.

Middle school math predicts high school graduation

If elementary school math can predict high school math, what can middle school math predict?

One longitudinal study examined the graduation patterns of nearly 13,000 students in an urban district to discover how middle school factors related to high school graduation. The results showed that only 13% of students who failed a math course in sixth grade graduated on time. An additional 6% graduated one year late. The remaining 81% had not graduated by the time the study ended.3

Sixth-Grade Math and Graduation

Moreover, failing a sixth-grade math course was a better predictor of failure to graduate than either a student’s race or status as an English Language Learner. In comparison, end-of-sixth-grade test scores were poor predictors of whether a student would drop out.

High school math predicts career goals

When it comes to math achievement, the high school years may be some of the most critical in a student’s academic career. We’re not trying to sound overdramatic, but research indicates a student’s math performance in these grades may affect the rest of their life.

To start with, there appears to be a relationship between high school students’ math achievement and their hopes and dreams for the future. A longitudinal study examined the career aspirations of “high-achieving” ninth graders (who attained 75% or better in their math courses) and “low-achieving” ninth graders (who attained less than 75% in their math courses).

After controlling for students’ perceptions of their own math competence, their overall GPA, and the education levels of their parents, the authors found ninth-grade math achievement had a significant effect on career aspirations—not just in ninth grade but even after high school graduation.4 Math achievement, specifically, seemed to affect career goals above and beyond overall academic achievement.

Low-math-achieving students not only started out with lower occupational aspirations, but also experienced a dramatic decline in their aspirations from mid-high school onward. High-math-achieving students also saw a decline in career aspirations, but started with higher overall aspirations and saw a more gradual decline throughout high school and postsecondary years, ending with career goals notably higher than their low-achieving peers.

Ninth-grade math achievement is a “critical filter” for students’ career goals.

The authors suggested that ninth-grade math achievement is a “critical filter” for students’ career goals and “low math achievement early in high school may steer adolescents away from the advanced math courses required by postsecondary education programs that lead to many higher-prestige career paths, not only in the physical science and technology fields, but also in health, commerce, and many social sciences.”

As we’re about to see, those advanced math courses in high school are particularly important when it comes to college and career outcomes.

High school math predicts college graduation, postsecondary degrees, and career earnings

A report that examined the long-term outcomes of thousands of students across the United States found clear connections between the highest level of math completed by the end of high school and the highest degree of education attained 10 years later.5 Only 3% of students who had completed vocational math but no higher-level math courses had earned a bachelor’s degree or higher, whereas 73% of students who had completed at least one calculus course held a bachelor’s degree or higher.

High School Math and Bachelor’s Degree

Furthermore, students who did not complete more-advanced math courses such as algebra or calculus were much more likely to drop out of high school or fail to earn a high school diploma.

High School Math and Graduation

For all ethnicities and all income levels, the higher the level of math courses a student completed, the more likely they were to graduate college with a bachelor’s degree. Completion of more-advanced math courses increased the predicted probability of college graduation even when the authors controlled for demographic traits, socioeconomic status, family and school characteristics, and overall measures of math ability (i.e., math GPA and grade 10 math test score).

Even 10 years after high school, math curriculum had an effect on annual earnings. Students who had completed a calculus course earned 65% more than students whose math education did not progress past a vocational math course. After accounting for ethnicity, gender, and other demographic traits; parental education and income; and high school characteristics, more-advanced mathematics courses still had an effect on annual earnings.

High School Math and Career Earnings

Moreover, math curriculum continued to have “striking” effects on earnings even after controlling for highest degree earned and college major as well as demographics, family, and school, suggesting that “there is a direct effect of math curriculum on labor market productivity, which works independently of the final degree attained.” Following this logic, if there were two individuals of the same ethnicity and gender, who come from similar families and attended the same high school, who both have the same degree in the same field (say a bachelor’s degree in biology), the one who completed a calculus course by the end of high school would likely earn more money than the one who did not!

On top of that, math courses still seemed to have an effect on earnings when courses taken in other subjects were considered. Advanced-level English courses increased earnings, but not as much as advanced algebra or calculus did. In addition, algebra/geometry, intermediate algebra, advanced algebra, and calculus all appeared to increase earnings more than average-level English courses did.

Note that for all these analyses, the total number of math courses completed wasn’t the key factor—it was the level of those courses. As the authors put it, “it is not simply the number of math courses that matters; what matters more is the extent to which students take the more demanding courses, such as algebra/geometry.”

Math’s path to college and career readiness

We’ve seen how math milestones can help students get on the path to college and career success. From mastering fractions and whole-number division by the end of elementary school to completing more-advanced math courses by the end of high school, each milestone a student achieves is one step closer to success in school and in life.

What does the overall path look like for students? Returning to the first study examined in this post, that author concluded that state standards (as they existed in 2007) were a good starting point.1 When he looked at the math achievement trajectories that led to completion of college, he found that attaining the typical state standard of math proficiency would put students on track for earning an associate’s degree or above from a two-year college. Students who met or exceeded National Assessment of Educational Progress (NAEP) proficient level for math or Trends in International Mathematics and Science Study (TIMSS) high benchmark for math were likely to earn a bachelor’s degree or above from a four-year college.

Considering that only 40% of fourth-grade students, 33% of eighth-grade students, and 25% of twelfth-grade students scored proficient or above on the 2015 NAEP math assessment,6 this may seem like a high bar to reach—but it’s not impossible.

Students can move toward college and career readiness incrementally, one math concept at a time. An analysis of students in grades 3–8 using a research-based math practice program found that 42% of the students who mastered an average of one to three subskills weekly reached college- and career-readiness benchmarks. In comparison, only 33% of the typical students—who did not use the program—were college and career ready. The highest level of college and career readiness was seen among students using the program who averaged mastery of four or more subskills per week; 58% of these students met proficiency benchmarks—almost double the rate of the typical students.

Math College and Career Readiness

Imagine what your students could achieve by mastering just one or two more subskills each week. For many, that small change could have big effects. However, there are hundreds of different math skills and even more math subskills. How do you know which ones are the most important for students to learn?

  1. Jody Steinhaus says:

    Having students who are able to explain their math thinking and reasoning to peers is important in the developmental growth of math sinkers and learners.

  2. Rita Platt says:

    This gives me some good ideas. We really haven’t used STAR Math like we should/could.

  3. Liana Ferrer says:

    Knowing which skills are mastered and which need to be worked on can be seen on the instructional report.

  4. Thonisha Davis says:

    My students seem to master 2 or 3 subskills a week. AM is not my primary resource so I use it when I can.

  5. Virginia Wiedenfeld says:

    I enjoyed learning more about the importance of taking as many math courses as you could! Thank you for the article!

  6. Andrea says:

    Math talk is important for the students to explain their thinking and make adjustments to it.

  7. carly says:

    As a 3rd grade teacher, I recognize the importance of filling in gaps, which research shows those gaps grow if not filled in by 3rd grade. I know that this is a foundational year from which future years will be build. I love when my students come back to share their math scores in the years after leaving 3rd grade. I appreciate the data AM provides and the practice that I can easily tie in with hands-on learning.

  8. Katie Wiltz says:

    This was a great article!!!

  9. Cathy Seale says:

    This is a great article that helps me remember the main things! Supporting student thinking is our main focus as we help all students master the needed skills.

  10. Shonda Hill says:

    It makes complete sense. When a child has a solid foundation, all tasks that follow will be easier.

  11. Lorrie says:

    I would like to see animated math learning tool for students in elementary school.

  12. Angela says:

    I teach middle school math so I found it interesting that 81% of students who do not pass 6th grade math do not graduate high school. It was a very interesting article.

  13. Sandra says:

    We could use more from STAR Math reports than we currently do. I think updated training that include the predictors would be eye opening for many teachers.

  14. Virginia Travis says:

    The instructional report is very important to keep track of the skills your students have mastered .

  15. Katy says:

    This article just explains why understanding math and doing math are two different things. Students need to know, understand, and use their math knowledge!

  16. Laura says:

    A great reminder on the importance of Math in our student’s lives!

  17. Alecia Walkuski says:

    It is very interesting to see how math, and college and career readiness are related.

  18. Amber AuBain says:

    I never thought about 9th grade being such a critical math year for students. Thanks for the great information!

  19. jason says:

    Interesting how data at various stages can predict outcomes later in life, but I fear this may force additional pressures on elementary students.

  20. Doug Abend says:

    If you think about it, this information makes sense. Math is cumulative. Certain years are benchmark years where all previous skills really need to come together. Students who can pull those strands together and make new math understandings will also do well in other areas.

  21. Renee Graham says:

    My current school does not use Accelerated Math. I was blessed to have it at a previous school. I really wish we could get it. It is an amazing way to differentiate math lessons.

  22. Nicole Erwin says:

    I appreciate the connection between skill at earlier ages to future success, but I hope that does not become a way to limit students (you can only do this because you only know this)

  23. Christine says:

    My school doesn’t use Renaissance math.

  24. s. bellomo says:

    i think it always circles back to fundamentals. A strong foundation is key to learning new concepts and ideas.

  25. Dvawn Maza says:

    Very good information and foundational skills are important!

  26. Veronica Gonzalez says:

    Information is very good and I do agree that when a child has a solid foundation, all tasks that follow will be easier.

  27. Ami K. Edwards says:

    I don’t have access to math program, but good ideas.

  28. I know where my students are struggling because they take RR star math. We also give them benchmarks and I focus on certain TEKS that students are lacking.

  29. P R says:

    Math is like a stepping stone of concept building. Basic skills have to be mastered in order to continue with the curriculum. We need to model the concepts. MOST OF ALL, we need to engage our students in applying the concepts.

  30. Krystal Dozier says:

    We do not currently use Accelerated Math. Previously, we used it and loved it! I feel that math talks are just as important as reading conferences.

  31. Lisa Capon says:

    I do not use Math programs in my class, but this was very informative

  32. Lauren Thrasher says:

    This is good information that validates some of the practices that we do in my school district.

  33. Kelly Barr says:

    I try to get my students into AM Live each week but the struggle to do so is real! I need to make a better effort to have students working in there at least 3 days a week to really see growth.

  34. Angela Domond says:

    As a fourth grade teacher, I find it very difficult to help my students master long number long division and fractions because of the limited amount of time that we have to spend on those lessons before moving on to a new chapter with a new concept and not really being able to review the previous chapters.
