After Jennifer Cooper had her daughter, her entire paycheck started going to daycare.
"There wasn't a single dollar left at the end," she said.
On weekends, she waited tables at the Melting Pot in Louisville. During the week, she coached volleyball and basketball, sometimes not leaving games until 9:30 p.m. Between the restaurant shifts and the late-night games, she never stopped to do the math on what an advanced degree could mean for her salary.
She'd been in the classroom for 25 years, most of them in Adams 12 Five Star Schools.
"I think I did what a lot of teachers do, which is just get into the grind of teaching," Cooper said. "Most teachers take out student loans to be able to pay for college. So as soon as you start teaching, you're trying to pay them off."
It took a financial advisor to show her what she'd been too busy to see. The gap between a teacher with a bachelor's degree, earning around $40,000, and one who has earned a master's degree plus additional graduate credits is nearly double.
Over a 25-year career, the difference can reach $350,000 or more.
With her eyes opened to the possibility, Cooper earned her master's in technology while teaching at Mountain Range High School. The salary bump was immediate, and so was the regret.
"After I did it, I really was like, why didn't I do this earlier?" she said.
She started showing her colleagues the same pay scale. The path to higher pay was straightforward on paper. Earn graduate credits by taking professional development courses, and the district moves you to a higher salary column.
A teacher who earned enough credits could add $5,000 or more to their annual salary. But the courses standing between teachers and that raise were expensive, disconnected from the classroom and taught by people who hadn't set foot in a school in years.
The system asked teachers to invest time and money in training that didn't help them teach, then rewarded them for enduring it.
Research-based paper after research-based paper'
"When I looked at all the classes I took beyond my master's, none of them were relevant to the classroom," she said. "It was really like research-based paper after research-based paper."
For instance, no one had ever offered her a course on how to support a student with dyslexia in her social studies classroom, or how to check whether reading materials matched a student's reading level.
Teachers are required to take ongoing courses and training to maintain their licenses and advance their careers, a process known as professional development.
Yet a national study by the Bill & Melinda Gates Foundation found that only 29% of teachers were highly satisfied with what was available.
When that training falls short, students feel it — an English language learner whose assignments were never adapted, a child with a learning disability whose teacher was never shown the tools that could help.
Cooper said those numbers reflect what she hears from teachers across the country: training feels like something done to them, not for them.
In 2018, she founded Happy Teacher Professional Development to build what she couldn't find. The Colorado-based company offers about 45 online, self-paced courses designed and taught by working classroom teachers. Individual courses start at $90.
Adams 12 teachers Jason and Samantha Sutterfield recently enrolled and invested a combined $8,000 in courses. They now earn an additional $18,000 a year, money that has helped them pay off debt and stay in a profession they love.
Training by salespeople, not teachers
Cooper pointed to her own school as an example. It purchased Magic School, an AI-powered classroom tool, a year and a half ago. The training was led by the company's marketing team. She said teachers were dropped into Zoom breakout rooms of four and told to discuss how they might use it.
"They didn't even show us how to log in," Cooper said.
A colleague from Jeffco who helps teach the platform through Happy Teacher told Cooper that she had never received district training on Magic School's student-facing features, even though the district has spent heavily on the program.
Cooper said the same was true in Boulder Valley. In each case, districts spent taxpayer money on the software, then left teachers to figure it out on their own.
When Colorado introduced a new behavioral health and special education training requirement for license renewal, Cooper said the mandate sparked panic among educators who hadn't been tracking the change.
Happy Teacher built a course to meet it, and now, more than 900 teachers have taken it.
What comes next
Cooper took a year of sabbatical during the pandemic as panicking teachers flooded Happy Teacher looking for help with remote instruction. But she came back to teaching because she “felt disconnected from the classroom.”
She now teaches two personal finance classes at Legacy High School and runs the company the rest of the time. All of Happy Teacher's instructors teach in active classrooms, a distinction Cooper calls the company's greatest strength.
Through a recent partnership with Upper Iowa University, teachers can apply up to 12 graduate credits toward a master of education degree that costs $10,000, a fraction of the roughly $50,000 national average.
Five years from now, Cooper wants to replicate what Happy Teacher has built in Colorado across the country.
For now, growth looks the way it always has for her: one teacher mentions a Happy Teacher course they enjoyed in the break room, and 10 colleagues sign up. Each one a step closer to a raise and armed with new knowledge to use in the classroom.
