The Truth About What Is the Average ACT Score in 2024: Data, Trends & What It Really Means

Published

The ACT isn’t just a number—it’s a gateway, a benchmark, and for many students, a source of anxiety. In 2023, over 1.6 million high schoolers took the test, each hoping their score would open doors to competitive universities. But when someone asks, "What is the average ACT score?" the answer isn’t as straightforward as it seems. The national average fluctuates yearly, but the real question is whether that average reflects your potential—or just the curve of a standardized test designed to sort applicants. The truth is, the average ACT score in recent years has hovered around 20.3 to 20.8, but what that number means for your admissions chances depends on where you’re applying. Elite institutions like Stanford or MIT rarely admit students below a 30, while mid-tier schools may accept scores as low as 22-24—if paired with strong essays and extracurriculars.

What’s often overlooked is that the ACT’s scoring system isn’t just about raw performance. A composite score of 20, for example, might mask a 28 in English and a 15 in Math, revealing gaps that colleges scrutinize. The test’s evolution—from its origins as a quick, multiple-choice alternative to the SAT to its current status as a critical admissions factor—has turned "what is the average ACT score?" into a question with layers. Understanding these nuances isn’t just about knowing the number; it’s about decoding how that number interacts with your academic profile, the schools you’re targeting, and the shifting landscape of college admissions.

The ACT’s scoring model, with its 1-36 scale, creates a psychological threshold: anything below 24 starts to feel "below average," even though the average itself is a moving target. Test prep companies exploit this by marketing "average-beating" strategies, but the reality is more complex. The average ACT score isn’t a static line—it’s influenced by participation rates, state mandates (like Texas’s requirement for all graduates), and even the year’s difficulty curve. For instance, in 2022, the average dipped slightly to 20.3 after years of gradual increases, a shift that sent ripples through admissions offices. The question then becomes: If the average is rising, does that mean you need a higher score to compete?

The Complete Overview of What Is the Average ACT Score

The average ACT score is a deceptively simple question with a surprisingly layered answer. Officially, the national composite average for the ACT in 2023 was 20.8, according to ACT, Inc. data. But this number is a composite of four sections—English, Math, Reading, and Science—each with its own average and range. For example, while the average Math score hovers around 20.6, the average English score is slightly higher at 21.1, reflecting historical strengths in grammar and rhetoric among test-takers. These averages are calculated annually from the 50th percentile of all test-takers, meaning half of students scored below and half above. However, the average isn’t the only metric that matters; the middle 50% range (from the 25th to 75th percentile) provides a clearer picture of what’s considered "competitive." In 2023, that range was 17-24, illustrating the gap between the average and the scores that actually get students into top-tier schools.

The confusion around "what is the average ACT score?" stems from how the test is used. Colleges don’t just look at whether your score is above or below the national average—they compare it to the middle 50% range of their admitted students. A school like the University of Michigan, for instance, had a middle 50% ACT range of 25-32 in 2023, meaning the average ACT score of 20.8 would place you in the bottom quartile for admissions. This discrepancy highlights why understanding the average is only the first step; the next is contextualizing it against the schools you’re targeting. Additionally, the ACT offers superscores, where colleges take your highest section scores from multiple test dates, further complicating the "average" narrative. A student with a 28 composite from one test and a 22 from another might still be admitted to a school that superscores, even if their raw average is closer to 25.

Historical Background and Evolution

The ACT’s scoring system was designed to be norm-referenced, meaning its difficulty adjusts to keep the average around 21—a deliberate choice to maintain consistency across decades. When the test launched in 1959, the average score was 18.6, but by the 1980s, it had climbed to 20.1 as test prep became more widespread. The 2000s saw another shift, with the average rising to 21.1 by 2010, partly due to increased participation in states like Texas and Florida, where the ACT became mandatory. This trend continued until 2016, when the average peaked at 21.0, before stabilizing around 20.3-20.8 in recent years. The reason for this plateau? A combination of test fatigue (students taking the ACT fewer times) and changing demographics, as more first-generation and low-income students—who historically scored lower—entered the pool.

The ACT’s evolution also reflects broader educational trends. The introduction of the ACT WorkKeys in the 1990s and later the ACT National Career Readiness Certificate expanded its use beyond college admissions, diluting the test’s academic rigor in some eyes. Meanwhile, the SAT’s optional essay section and the ACT’s mandatory Science section (which many students struggle with) created a divide in how the two tests are perceived. Critics argue that the ACT’s average score is artificially inflated because it’s easier to game the system—with strategies like guessing heavily in Science or memorizing passage-based questions—whereas the SAT’s math section demands deeper conceptual understanding. This debate over "what is the average ACT score?" isn’t just about numbers; it’s about whether the test measures what colleges truly value.

Core Mechanisms: How It Works

The ACT’s scoring algorithm is a blend of raw scores, percentiles, and curve adjustments designed to keep the average within a predictable range. Each of the four sections is scored on a 1-36 scale, with the composite score calculated by averaging the four section scores. However, the percentile rank—which shows how you compare to other test-takers—is what colleges often prioritize. For example, a 24 composite might correspond to the 67th percentile, meaning you outperformed 67% of test-takers, but that doesn’t translate directly to admissions odds without knowing the school’s benchmark. The ACT also uses equating, a statistical process to adjust scores if a test form is harder or easier than average, ensuring the average stays around 21.

What’s less discussed is how the Science section skews the average. Unlike the SAT, which dropped its Science section in 2005, the ACT retains it, and its average score (20.3) is consistently the lowest of the four sections. This drags down composite scores for students who struggle with data interpretation and graph analysis—skills not always emphasized in high school curricula. The English section, by contrast, has the highest average (21.1), likely because its grammar and rhetoric questions align more closely with standardized test prep. Understanding these mechanics is crucial when interpreting "what is the average ACT score?"—because a student with a 28 in Math but a 16 in Science might have a 22 composite, yet their strengths in one area could still make them competitive for schools that value subject-specific excellence.

Key Benefits and Crucial Impact

The average ACT score isn’t just a statistical footnote—it’s a reflection of college readiness, educational equity, and admissions strategy. For students aiming for top 10% schools, where the average admitted ACT score hovers around 30-34, knowing the national average is only half the battle. The real advantage comes from understanding how your score stacks up against school-specific benchmarks. A student with a 25 ACT might be in the 80th percentile nationally, but at a school like University of Chicago, where the middle 50% range is 32-35, that same score could be a dealbreaker. This is why elite test prep companies focus on pushing students beyond the average—because in admissions, the average is the floor, not the ceiling.

The impact of the ACT extends beyond college doors. Employers and scholarship committees increasingly use ACT scores as a proxy for academic potential, especially in fields like engineering and medicine. A 30+ ACT can open doors to National Merit Scholarships, while a 22-24 might qualify for state-specific aid. Even in the age of test-optional policies, many schools still prefer to see ACT/SAT scores, making the average a critical reference point. The test’s predictive power lies in its ability to correlate with first-year college GPA, though critics argue this is more true for low-income students than for affluent test-takers who benefit from expensive prep courses.

Major Advantages

  • Clarity in Admissions Benchmarks: Knowing the average ACT score helps students set realistic targets based on their target schools’ middle 50% ranges. For example, a 26 ACT is above the national average but may still be below the 30+ threshold for Ivy League schools.
  • Identifying Strengths and Weaknesses: The ACT’s section-by-section breakdown reveals where students excel (e.g., English) and need improvement (e.g., Science), allowing for targeted test prep.
  • Leveraging Superscores: Many colleges accept the highest section scores from multiple test dates, meaning a student with a 28 in Math and a 22 in Science could still achieve a 25 composite if the school superscores.
  • Scholarship and Financial Aid Eligibility: Many merit-based scholarships (e.g., ACT National Merit) require scores above the 90th percentile, making the average a useful benchmark for aspiring applicants.
  • Comparative Advantage Over SAT: In states where the ACT is mandatory (e.g., Texas, Florida), students often perform better on it due to familiarity, giving them an edge in admissions where both tests are accepted.

The ACT’s future hinges on two competing forces: declining test participation and increased reliance on alternative metrics. As more states adopt test-optional policies, the average ACT score could drop further, as only the most competitive applicants take the test. However, colleges still need a way to standardize applicants, and the ACT’s digital format (launched in 2020) may help it stay relevant by offering faster, more flexible testing. Innovations like ACT’s "Focus" program, which provides personalized feedback, could also shift the conversation from "what is the average ACT score?" to "how can you maximize your potential?"

Another trend is the ACT’s expansion into career readiness, with programs like ACT WorkKeys gaining traction in workforce development. If the test continues to blur the line between college admissions and job preparedness, its scoring averages may become even more fragmented. Meanwhile, the SAT’s return to a 1600 scale and the ACT’s push for section-level reporting suggest a future where customized scoring—rather than a single average—becomes the norm. For students today, this means the average ACT score is less about memorizing a number and more about strategizing how to stand out in an evolving admissions landscape.

Conclusion

The average ACT score is more than a statistic—it’s a mirror reflecting educational equity, test-taking strategies, and the shifting priorities of colleges. While the national average sits at 20.8, what truly matters is how that number interacts with your goals. A 22 ACT might be above average nationally but below the threshold for many competitive schools, making test prep and retakes essential. The key takeaway? The average is a starting point, not a finish line. Students who understand the nuances—from section-specific strengths to superscoring opportunities—are the ones who turn a "good enough" score into a competitive advantage.

As colleges continue to rethink admissions, the ACT’s role may evolve, but its scoring system will likely remain a critical tool for assessment. For now, the best approach is to aim higher than the average, because in the world of college admissions, mediocrity is the only thing that’s truly average.

Comprehensive FAQs

Q: What is the average ACT score in 2024, and how has it changed over the years?

A: The national average ACT composite score in 2024 is approximately 20.8, down slightly from its peak of 21.0 in 2016. Historically, the average has fluctuated between 18.6 (1959) and 21.1 (2010), with recent years showing stabilization around 20.3-20.8. The decline in recent years is attributed to fewer test-takers, test fatigue, and demographic shifts in participation.

Q: Is a 20 ACT score good enough for college admissions?

A: A 20 ACT is above the national average (which is ~20.8), but whether it’s "good enough" depends on your target schools. For mid-tier public universities, a 20-22 may suffice, but selective private schools typically require 25+. Always check the middle 50% range of admitted students for your target colleges.

Q: How does the ACT average compare to the SAT average?

A: The ACT average (20.8) converts roughly to a SAT total of 1060 (on the 1600 scale). However, section-level comparisons vary: ACT Math (~20.6) aligns closely with SAT Math (~530), while ACT Science (~20.3) is often a weak point for test-takers. The SAT’s Reading and Writing sections tend to have higher averages than ACT English.

Q: Can I improve my ACT score to beat the average?

A: Yes. Targeted test prep—especially in weak sections like Science—can boost scores by 3-6 points. Strategies include:

  • Diagnostic tests to identify weak areas.
  • Content review (e.g., algebra, grammar rules).
  • Time management drills for pacing.
  • Retaking sections (via superscoring) to maximize composite scores.

    • Q: Do colleges care if my ACT score is above or below the national average?

    A: Not directly. Colleges care about how your score compares to their admitted students’ scores. A 22 ACT might be above average nationally but below the 25+ threshold for many selective schools. Always research school-specific benchmarks rather than relying on the national average.

    Q: What’s the highest possible ACT score, and how many people achieve it?

    A: The highest ACT composite score is 36, achieved by ~0.001% of test-takers (about 1,600 students per year). Perfect section scores (36 in each) are even rarer, with fewer than 100 students achieving this annually. Most 36-composite scorers excel in English and Math but may have slightly lower Science scores.

    Q: Is the ACT getting harder or easier over time?

    A: The ACT adjusts difficulty annually to maintain an average around 21, but section-specific trends exist. Science is consistently the hardest, while English is the easiest. The test’s curve is designed to keep the average stable, meaning difficulty doesn’t necessarily increase—but sectional challenges (like new question types) can make certain areas feel harder.
