The purpose of this paper is to summarize the key findings from a critical review of relevant US research to determine whether teachers, on average, improve in their effectiveness as they gain experience in the teaching profession.,This paper is based on the authors’ review of 30 studies published since 2003 that analyze the effect of teaching experience on student outcomes in the USA.,The authors find that: teaching experience is positively associated with student achievement gains throughout much of a teacher’s career; as teachers gain experience, their students are more likely to do better on measures of success beyond test scores; teachers make greater gains in their effectiveness when they teach in a supportive, collegial environment, or accumulate experience in the same grade, subject or district; and more experienced teachers confer benefits to their colleagues.,A renewed look at this research is warranted due to advances in methods and data systems that have allowed researchers to examine this question with greater sophistication.

本文的目的是总结对美国相关研究进行批判性审查的主要发现，以确定教师在获得教学专业经验时平均而言是否能提高他们的效能。，本文基于作者的评论在2003年以来发表的30项研究中，分析了教学经验对美国学生成果的影响。作者发现：在整个教师职业生涯中，教学经验与学生成就的获得成正比；随着教师积累经验，他们的学生更有可能在测验成绩以外的成绩上取得更好的成绩；在支持性的大学环境中任教或积累相同年级，学科或地区的经验时，教师的效能会得到更大的提高；
