Teacher Quality and Student Achievement a Review of State Policy Evidence Previous Research
Introduction
A central value of public education in the 21st century holds that all children can learn. Yet this perspective has not necessarily carried over to social attitudes near teachers. While the inquiry and policy communities agree that teachers improve quickly early in their careers, there is debate most whether teachers continue to larn after they gain significant experience in the classroom. That is, exercise teachers, on average, proceed to improve in their effectiveness as they gain experience in the teaching profession?
The reply to this question has pregnant policy implications. For example, is it an equity problem that low-income students and students of colour are more probable to be taught by the least experienced teachers and to attend schools with loftier rates of teacher turnover? Should we invest in professional development and learning opportunities for more experienced teachers, or focus these resources on novice teachers only? Should experience be rewarded through salary schedules that tie pay to feel in an effort to retain veteran teachers? Should policy be focused on building teaching equally a long-term profession, or on recruiting and preparation a curt-term instruction workforce?
This cursory documents a review of research finding that, indeed, teachers do continue to improve in their effectiveness as they gain feel in the didactics profession. We detect that educational activity experience is, on boilerplate, positively associated with student accomplishment gains throughout a instructor'southward career. Of course, variation in teacher effectiveness exists at every stage of the education career: non every inexperienced teacher is, on average, less effective, and non every experienced instructor is more effective.
Some previous studies concluded that teachers plateau in their effectiveness early in their careers. Our findings are different for ii major reasons. Starting time, advances in information systems that tin can track teachers over time and match individual teachers to their students' outcomes have allowed researchers to use a amend inquiry method, called "instructor stock-still effects." This method allows researchers to compare a teacher to herself over time every bit she gains more feel. In contrast, older studies often used less precise methods, such as cross-exclusive analyses that use a "snapshot" approach to compare singled-out cohorts of teachers with dissimilar experience levels during a single schoolhouse year (see Figure 1).
Second, some studies limit the ranges of experience that they analyze. For example, some studies examine the benefits of teaching feel for only the outset few years of a instructor's career (e.g., years 0-v). Other studies group teachers into ranges of experience (e.g., years 0–iv, 5–12, 13–20, 21–27). This can be problematic because it assumes that teacher productivity does non change within each of the ranges of feel.
The policy importance of this finding is heightened given the current context in which the education workforce has become less experienced. The nigh recent national data suggest that compared to prior decades, a greater proportion of the instruction workforce has less than 5 years of feel. In improver, this finding raises significant equity concerns considering inexperienced teachers tend to exist highly concentrated in underserved schools, where students need quality teachers nearly. For example, Black, Latino, American Indian, and Native-Alaskan students are three to four times more likely to nourish schools with college concentrations of first-yr teachers than White students. English language learners too attend such schools at college rates than native English language speakers. In addition, students in the highest poverty schools are 50% more likely to accept a instructor with less than four years of experience when compared to students in the lowest poverty schools.
Our research does not signal that the passage of fourth dimension will make all teachers better or incompetent teachers effective. The benefits of teaching experience will be best realized when teachers are carefully selected and well prepared at their point of entry into the teaching workforce, as well as intensively mentored and rigorously evaluated prior to receiving tenure. This volition ensure that those who enter the professional tier of educational activity have met a competency standard from which they tin continue to expand their expertise throughout their careers.
Although teachers improve at greater rates during the first few years of their careers, teachers proceed to meliorate, admitting at bottom rates, throughout their careers.
Findings
We examined 30 studies that analyzed the effect of teaching experience on educatee outcomes in Thou–12 public schools in the United States, every bit measured by student standardized test scores and not-examination metrics when available. We reviewed studies that examined teaching experience published in peer-reviewed journals and past organizations with established peer-review processes since 2003, when the use of teacher fixed effects methods became more prevalent. The studies correspond diverse populations from different parts of the state, including California, Florida, Kentucky, New Jersey, New York, and North Carolina and include studies of both math and reading at the unproblematic-, middle-, and loftier-schoolhouse levels. Our review led us to four findings.
Teachers whose peer teachers had more experience tended to have improved educatee outcomes.
i. Pedagogy experience is positively associated with student achievement gains throughout a teacher'south career. The gains from feel are highest in teachers' initial years, just go on for teachers in the second and frequently third decades of their careers.
Studies generally have establish that although teachers improve at greater rates during the first few years of their careers, teachers keep to improve, admitting at bottom rates, throughout their careers. In Table 1, nosotros summarize the findings of the 30 studies we reviewed. Of these studies, 28 institute that educational activity feel is positively and significantly associated with teacher effectiveness. Most two-thirds of the studies clarify longitudinal datasets with teacher fixed effects, which is our preferred research method because it allows for the examination of whether a given teacher becomes more constructive over time (see Figure 1). Amid this body of enquiry, all eighteen studies found a positive and statistically meaning relationship between educational activity experience and student performance on standardized tests.
two. As teachers gain experience, their students are also more likely to exercise better on other measures of success beyond examination scores, such equally school attendance.
Researchers have recently begun to study whether more experienced teachers produce academic benefits for students that go beyond exam scores. One study of 1.2 million middle school students in N Carolina analyzed student data on test scores as well as other noncognitive outcomes: absences, disciplinary offenses, amount of time students spent reading for pleasure, and corporeality of time students spent completing homework. The study controlled for a variety of characteristics, including race, eligibility for complimentary and reduced-toll dejeuner, and prior twelvemonth accomplishment. Experienced teachers positively influenced several noncognitive outcomes. For example, existence taught past English Language Arts (ELA) teachers with greater feel was associated with students spending more than time reading for pleasure, and math teachers' experience was associated with fewer disciplinary offenses.
As teachers gain experience, their students are less likely to miss schoolhouse.
One of the most striking findings was that as teachers gain feel, their students are less probable to miss school. This finding is of import because of the strong show linking high rates of absenteeism with negative long-term educational outcomes. Specifically, the N Carolina study found that one year of experience immune an ELA instructor to reduce the proportion of students with loftier absenteeism by 2 per centum points, and that a teacher "who obtains over 21 years of feel on boilerplate reduces the incidence of loftier student absenteeism by xiv.5 percent points." The study constitute similar furnishings for math teachers.
Importantly, more experienced teachers provided the greatest benefit to higher risk, chronically absent-minded students. For case, ELA and math teachers with more than 21 years of experience reduced the number of students with over three absences by 6 and 4 percent, respectively, simply reduced the number of students with over 17 absences by three times equally much.
3. Teachers make greater gains in their effectiveness when they teach in a supportive and collegial working environment, or accumulate feel in the aforementioned grade level, subject, or district.
Recently, research has begun to show that teachers' rate of improvement over fourth dimension also depends on the supportiveness of their professional working environment. In addition, a few studies have institute that teachers with prior experience in the same grade level, subject expanse, or district show greater returns to experience than those with less relevant prior experience.
A recent large-scale study of math students over 10 years in North Carolina'south Charlotte-Mecklenberg School District examined how teachers' improvement over fourth dimension was related to their school environment. The study showed that teachers who work in schools with strong professional environments improve at faster rates than their peers working in schools with weaker professional environments. The study found that tenth-twelvemonth teachers working in more supportive schools—characterized by a trusting, respectful, condom, and orderly environment, with collaboration amongst teachers, schoolhouse leaders who support teachers, time and resources for teachers to better their instructional abilities, and teacher evaluation that provides meaningful feedback—become substantially more effective than teachers working in schools that have few of the above characteristics (come across Effigy 2).
4. More experienced teachers confer benefits to their colleagues and to the school every bit a whole, every bit well as to their own students.
Research indicates that teachers whose colleagues are more experienced are more than effective than those whose colleagues are less experienced. This suggests that more experienced teachers provide of import additional benefits to their school community beyond increased learning for the students they teach. A study using data from tertiary- through fifth-form students and their teachers in North Carolina over an 11-year period found that teachers whose peer teachers had more experience tended to accept improved student outcomes. The study too found that novice teachers benefit well-nigh from having more than experienced colleagues. In improver, the study found that the quality of a teacher's peers the twelvemonth before, and even 2 years before, afflicted his or her current students' achievement.
Policy Recommendations
These research findings show the benefits of more experienced teachers, on average, for both students and schools and advise a number of implications for policymakers and educators at the federal, land, district, and schoolhouse levels. Most importantly, policymakers should focus on program and investment strategies that build an experienced education workforce of high-quality individuals who are continually learning. Accomplishing this goal volition require the implementation of policies and practices to increase teacher memory and reduce turnover in schools. Nosotros offering the post-obit three recommendations:
1. Increase stability in instructor job assignments.
Teachers who have repeated feel instruction the same course level or subject area improve more rapidly than those whose experience is in varied class levels or subjects. Of form, many factors influence job assignment decisions, including teachers' desires for professional growth and new challenges, also as principals' needs for flexibility in management. Schoolhouse leaders, however, should be educated about the increased benefits of specific teaching experience and consider this in their decisions nearly teaching assignments.
2. Create conditions for stiff collegial relationships among school staff and a positive and professional working environment.
Increasing opportunities for collaboration and for a more productive working surroundings is smart policy because of the hope this holds for increased teacher memory and considering the benefits of feel are greater for teachers in strong professional person working environments. Collegiality is hard to legislate, merely there are nonetheless concrete steps that policymakers can take. Commune and school leaders can facilitate scheduling changes to allow for regular blocks of fourth dimension for teachers who teach the same subject or who share groups of students to collaborate and programme curriculum together. Federal and state policymakers can promote quality schoolhouse leadership through the development of chief career pathways in which talented teachers are proactively recruited and intensively trained and coached by an skillful primary.
3. Strengthen policies to encourage the equitable distribution of more experienced teachers, and discourage the concentration of novice teachers in high-demand schools.
The new Every Educatee Succeeds Act requires states to develop plans describing how low-income students and students of color "are not served at disproportionate rates by ineffective, out-of-field, or inexperienced teachers" and to evaluate and publicly report on their progress in this area. Districts are required to "identify and accost" teacher disinterestedness gaps. As the U.S. Department of Education works to implement these provisions, much will depend on how the term "inexperienced teacher" is defined. The Department of Education should strengthen its enforcement of these provisions and ascertain the term "inexperienced" instructor to include teachers who, at a minimum, are in their first or second yr of pedagogy. Such a definition would be consistent with the definition used by the Department in its Ceremonious Rights Data Collection, which provides of import data on the concentration of showtime-year and second-year teachers in every school in the nation.
Other strategies for developing an experienced education workforce that is continually learning have been well documented elsewhere, such as providing clinically based grooming and high-quality mentoring for beginners, also as career advocacy opportunities for practiced, experienced teachers. As documented here, our review of the latest research underscores that these investments tin pay big dividends for our nation's students.
