The Surprising Teacher Factors that Actually Impact Teen Reading Achievement

As parents and educators, we often wonder: what truly makes a difference in helping teenagers become strong readers? Is it about hiring teachers with the most advanced degrees? Should we focus on reducing class sizes? Or is teacher experience the key?

My recent research with Dr. Kouider Mokhtari provides some surprising answers to these questions - with findings that challenge conventional wisdom about what makes for effective reading instruction.

The Surprising Truth About What Works (And What Doesn't)

Our study examined data from the 2018 Program for International Student Assessment (PISA), analyzing how various teacher characteristics and school composition factors influenced the reading scores of 15-year-old students across the United States.

Here's what we discovered:

What Really Makes a Difference:

1. Teacher experience matters - Each additional year of teaching experience was positively associated with higher student reading scores. Veteran teachers with extensive classroom time had students who performed better on reading assessments.
2. Teachers with education degrees outperform those without - Students taught by teachers who had formal education degrees showed significantly higher reading scores than those taught by teachers without such specific training.
3. Schools with more masters-degree teachers saw better results - Schools with higher percentages of teachers holding master's degrees had students with stronger reading performance.

What Doesn't Seem to Help:

1. Full-time teachers don't necessarily produce better results - Contrary to expectations, students taught by part-time teachers actually showed higher reading scores than those with full-time instructors.
2. Older teachers don't automatically mean better outcomes - Teacher age was negatively correlated with reading scores, suggesting that younger teachers might bring advantages to reading instruction.
3. Teacher certification doesn't guarantee better reading scores - Schools with higher percentages of fully certified teachers actually showed lower average reading scores, challenging conventional thinking about certification requirements.
4. Recent professional development had little impact - Teachers' participation in professional development during the previous 12 months showed no significant relationship to student reading scores.

Unpacking the Age Paradox

One of our most intriguing findings reveals what appears to be a contradiction: while more experienced teachers produce better reading outcomes, older teachers are associated with lower reading scores. How can both be true?

This suggests that the relationship between teacher age and effectiveness is complex. Younger teachers might bring fresh teaching approaches and closer connections to contemporary adolescent culture, helping them engage teenage readers more effectively. Yet the skills that come with experience still provide meaningful advantages.

The message? Schools might benefit from age-diverse teaching teams that combine the enthusiasm and contemporary approaches of younger teachers with the wisdom and classroom management skills of veterans.

The Part-Time Teacher Advantage

Perhaps our most surprising finding was that part-time teachers were associated with higher student reading achievement than their full-time colleagues. While counterintuitive, this might be explained by several factors:

• Part-time teachers may experience less burnout and maintain higher motivation
• They might bring specialized expertise from other professional roles
• Their teaching schedules might allow for more focused preparation time

For school administrators, this suggests that strategic use of qualified part-time reading instructors could potentially enhance student outcomes.

What Schools Should Focus On

Based on our findings, schools looking to improve adolescent reading achievement might consider:

1. Prioritizing education degrees in hiring - Teachers with specific education training showed better results than those without.
2. Creating mentoring systems - Pairing experienced teachers with newer colleagues could maximize the benefits of both experience and fresh approaches.
3. Reconsidering class structures - The conventional wisdom about smaller class sizes didn't hold up in our study; schools may need to think differently about how they allocate teaching resources.
4. Investing in advanced degrees - Schools with more teachers holding master's degrees showed better reading outcomes, suggesting potential benefits from supporting teachers in pursuing advanced education.

Beyond the Individual Teacher

Our research also examined school-level factors that influence reading achievement. We found that schools with higher percentages of teachers holding master's degrees tended to have students with better reading performance overall.

Interestingly, these schools also generally had lower student-teacher ratios, suggesting that the combination of well-educated teachers and more individualized attention creates powerful opportunities for student growth.

However, the story isn't simple. Schools with more fully certified teachers actually showed lower average reading scores - perhaps indicating that formal certification alone doesn't capture the qualities that make teachers effective at promoting reading achievement.

The Big Picture

What emerges from our study is a nuanced view of what matters in adolescent reading instruction. Rather than simple formulas about teacher qualifications or class sizes, effective reading education seems to depend on a complex interplay of factors.

Teacher experience and education both matter significantly, but so do less measurable qualities like enthusiasm, adaptability, and the ability to connect with teenage readers. Schools need to look beyond simple metrics when building teaching teams that can effectively support adolescent literacy.

Why This Matters

Reading proficiency is a fundamental skill that impacts academic success across all subjects. For 15-year-olds, strong reading abilities also predict future educational attainment, career success, and even lifelong learning habits.

By identifying the teacher factors that truly impact reading achievement, our research provides guidance for educational leaders making critical decisions about:

• Teacher hiring and assignment
• Professional development investments
• School staffing structures
• Resource allocation

These insights can help schools make evidence-based decisions that maximize their impact on student reading achievement, ultimately preparing more students for success in an increasingly text-heavy world.

The Bottom Line

Our research challenges some conventional assumptions about what makes for effective reading instruction at the high school level. While teacher experience and education degrees remain powerful positive factors, other commonly assumed requirements like full-time status, professional development, and certification don't show the expected impact.

For parents, understanding these factors can help in supporting their teenagers' reading development and appreciating the complex classroom dynamics that influence achievement. For educators and policymakers, these findings provide valuable guidance for creating more effective learning environments where adolescents can develop the reading skills they need for future success.
