Sure, it seems obvious that raising teacher pay makes a difference. But, it’s nice to have some evidence to back that claim up. Especially in a state where teachers now earn 4.4% less than they did back in 2009.

We Are Teachers has put together a list of six benefits of boosting teacher pay. Here are some highlights:

A majority (76%) of responders to a TIME poll said they agreed that many people won’t go into teaching because it doesn’t pay enough. This means fewer graduates of teacher education programs, and fewer teachers looking to fill the increase in demand for teachers.

Unsurprisingly, teacher pay has been shown to reduce turnover (which, in turn, increases student performance). Turnover is about 16% each year, and around 8% of teachers annually leave the profession entirely as opposed to moving to another school.

For example, a study in San Francisco found that when the salary for teaching was increased, the size and quality of teacher applicants increased.

Teachers are 30% more likely than non-teachers to have a second job. It goes without saying that raising teacher pay so teachers didn’t have to work a second job would boost teacher morale and help them stay focused on their classrooms.

In some states, teacher salaries are so low that teachers routinely qualify for public benefits like food stamps or public health care programs (like children’s health insurance programs). This is especially true for teachers who are the primary breadwinner in their family or have large families.

When teachers get paid more, students do better. In one study, a 10% increase in teacher pay was estimated to produce a 5 to 10% increase in student performance. Teacher pay also has long-term benefits for students. A 10% increase in per-pupil spending for each of the 12 years of education results in students completing more education, having 7% higher wages, and having a reduced rate of adult poverty. These benefits are even greater for families who are in poverty.
