Excerpts of the piece appear below:<\/p>\n\n\n\n<p>The key takeaways: Students often do better in smaller classes. But there\u2019s no agreement on exactly how much better, and it remains an open question whether or not class size reduction is a particularly good use of funds that could go elsewhere.<\/p>\n\n\n\n<p>All told, \u201cthe impact of smaller classes would depend on many factors,\u201d said Northwestern University economist Diane Schanzenbach, \u201cincluding whether funds are reduced for other student supports, the quality of the newly hired teachers needed to staff the smaller classes, and adequate availability of classroom space.\u201d<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Smaller does seem better when it comes to class size.&nbsp;<\/strong><\/h3>\n\n\n\n<p>The most famous and rigorous study of class size reduction took place in Tennessee beginning in 1985, when some kindergarten students were randomly assigned to unusually small classes through third grade. Test scores in the classes of 13 to 17 students quickly <a href=\"https:\/\/www.jstor.org\/stable\/2587015\">surpassed<\/a> scores in the larger classes of 22 to 25. Those gains <a href=\"https:\/\/www.journals.uchicago.edu\/doi\/10.1086\/605103\">persisted<\/a> for years.<\/p>\n\n\n\n<p>A few studies have also found other benefits, with smaller classes leading to greater classroom <a href=\"https:\/\/journals.sagepub.com\/doi\/full\/10.3102\/0162373710392370\">engagement<\/a> and higher <a href=\"https:\/\/www.sciencedirect.com\/user\/identity\/landing?code=DxF__uh_WpkGpe0lFiTHEFtvG8C-NRnlt-BkiEVW&amp;state=retryCounter%3D0%26csrfToken%3D2d7091dd-113e-477c-8048-a886e8649e8e%26idpPolicy%3Durn%253Acom%253Aelsevier%253Aidp%253Apolicy%253Aproduct%253Ainst_assoc%26returnUrl%3D%252Fscience%252Farticle%252Fabs%252Fpii%252FS0272775712000271%26prompt%3Dnone%26cid%3Darp-03452fa7-a037-43b6-ae2f-2c5df5e7a9e7\">attendance<\/a>. In Tennessee, researchers later found that students in smaller classes in early grades were also <a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/abs\/10.1002\/pam.21715\">more likely<\/a> to attend and graduate from college.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>It\u2019s not clear how big those benefits are, though<\/strong><\/h3>\n\n\n\n<p>These studies do not agree on how much improvement schools can expect from smaller class sizes. In some research, the impact of small classes is more modest than the large gains seen in Tennessee. There are also a few instances where smaller classes didn\u2019t seem to improve test scores at all, including in studies in <a href=\"https:\/\/www.jstor.org\/stable\/2586924\">Connecticut<\/a> and <a href=\"https:\/\/www.sciencedirect.com\/user\/identity\/landing?code=DxF__uh_WpkGpe0lFiTHEFtvG8C-NRnlt-BkiEVW&amp;state=retryCounter%3D0%26csrfToken%3D2d7091dd-113e-477c-8048-a886e8649e8e%26idpPolicy%3Durn%253Acom%253Aelsevier%253Aidp%253Apolicy%253Aproduct%253Ainst_assoc%26returnUrl%3D%252Fscience%252Farticle%252Fabs%252Fpii%252FS0272775712000271%26prompt%3Dnone%26cid%3Darp-03452fa7-a037-43b6-ae2f-2c5df5e7a9e7\">Florida<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Smaller classes mean hiring lots of teachers, which is complicated<\/strong><\/h3>\n\n\n\n<p>Substantially reducing class size generally requires schools to go on a hiring binge in order to staff the new classes \u2014 and those new teachers are often less experienced and effective than their peers. That means the benefits from lower class size may be partially counteracted by reductions in teacher quality, which has been shown in studies from <a href=\"https:\/\/www.jstor.org\/stable\/20648893\">California<\/a> and <a href=\"https:\/\/ny.chalkbeat.org\/2017\/7\/26\/21100717\/nyc-class-size-limits-could-boost-learning-but-in-practice-they-often-don-t-a-new-study-explains-why\">New York City<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Lowering class sizes comes with tradeoffs<\/strong><\/h3>\n\n\n\n<p>Some argue that putting resources into reducing class sizes \u2014 which requires more teachers and often additional classroom space \u2014 is misguided. Schools should focus on getting and keeping <em>better<\/em> teachers, not simply adding teachers, with the resources they have, they argue.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>There\u2019s still more to learn about how class sizes affect kids, but the perspectives of teachers and parents should be taken seriously<\/strong><\/h3>\n\n\n\n<p>In education policy circles, you\u2019ll often hear confident claims about class size reduction.
