How hard should it be to become a teacher?
It鈥檚 an ongoing debate, with proponents of higher barriers to entry arguing they鈥檙e necessary to ensure quality candidates鈥攁nd skeptics saying they unfairly shut out prospective 糖心动漫vlog who could be effective in the classroom. The research on certification requirements, licensing exams, and other professional screening mechanisms generally points to tradeoffs, rather than clear-cut answers.
When the pandemic began five years ago, it presented a natural experiment to study the question in more depth. Many states relaxed their teacher licensure rules and created emergency certification processes, removing requirements for prospective 糖心动漫vlog to take the exams that they would have otherwise had to pass.
Studies of this time period out of several states, including Massachusetts and New Jersey, showed that, in the wake of these policies, teachers鈥� performance held steady, and a more racially diverse group of candidates entered the profession.
But two from the Center for Analysis of Longitudinal Data in Education Research, or CALDER, at the American Institutes for Research present a more complicated picture.
Nationwide, there鈥檚 no definitive evidence that emergency waivers resulted in large numbers of new teachers entering the profession. And in one state, Massachusetts, where the emergency licensing process remained in place past 2022, teacher performance of newly hired teachers declined over time.
Taken together, the research provides more evidence of how the pandemic period affected the composition of the teaching profession, and offers clues about how permanent changes to licensure requirements could play out for student achievement.
It鈥檚 possible that the comparable performance that some states initially saw between traditionally licensed and emergency licensed teachers wouldn鈥檛 last if those changes were to become permanent, said Dan Goldhaber, the director of CALDER and an author on both papers.
鈥淭hat is what we saw initially, but it isn鈥檛 what we saw downstream,鈥� he said.
Mixed teacher effectiveness outcomes
To determine the overall change in teachers entering the profession, the researchers analyzed federal teacher workforce data from all 50 states and the District of Columbia, comparing measures of teacher supply鈥攕uch as initial licenses awarded, and graduates from teacher-preparation programs鈥攂etween states that offered flexibility in licensure test requirements in 2020 and states that did not. They controlled for a series of demographic and economic factors.
鈥淲e do not find definitive evidence that states that put in place waivers of licensure tests saw increases in teacher supply,鈥� Goldhaber said.
That finding comes with a caution, though, he added. Because of statistical limitations, the research can only determine there weren鈥檛 large effects. It鈥檚 possible there were smaller increases in the teacher workforce that the analysis doesn鈥檛 capture, he said.
It鈥檚 also possible that the temporary nature of the waivers influenced the findings. 鈥淧eople are not that likely to make career decisions based on a short-term regulatory change,鈥� Goldhaber said.
The other CALDER paper, a research brief, examined who received emergency teaching licenses in five states that instated pandemic-era policies: Maryland, Massachusetts, New Jersey, Ohio, and Washington state.
They found that teachers who entered the profession under these licenses were, on average, more racially diverse than their peers who went through a traditional certification process from 2017 onward. These emergency-licensed teachers were also more likely, in all but one state, to work in schools serving larger shares of Black and Hispanic students, and students from low-income families.
In the school year immediately after these policies were put in place, teachers who had emergency certification and those who had regular certification performed about the same鈥攖hey scored similarly on measures of teacher effectiveness, and received similar performance ratings.
But in Massachusetts, which did not reinstate its testing requirements until 2023, teachers who went through emergency certification in later years were less effective in math and science.
The study, the researchers write, 鈥渦nderscores the idea that loosening licensure rules alone is an incomplete鈥攁nd, in some cases, potentially counterproductive鈥攕trategy for reshaping the composition and quality of the teacher workforce.鈥�
Some argue for widening pathways to the profession
Still, some experts say there鈥檚 still not enough evidence to suggest that testing requirements need to continue in their current form.
鈥淚t鈥檚 not a slam dunk that the licensure requirements are definitely boosting teacher quality, but they are definitely limiting supply, especially for teachers of color,鈥� said education analyst Chad Aldeman.
Aspiring teachers of color fail these tests at higher rates than their white peers, and some researchers have argued that they don鈥檛 capture important components of success in the profession, like the ability to build healthy relationships with students.
Research on licensure tests shows that, in most cases, scoring higher on the test means teachers will be more effective in the classroom. But there鈥檚 still a 鈥渞easonable argument to be made鈥� for widening pathways into the profession, Alderman said.
鈥淚鈥檓 willing to tolerate some risk of lower performance, for the benefit of greater supply and greater diversity,鈥� he said.
