WAIANAE, Hawaii – Jonathan Sager was an idealistic 22-year-old recent college graduate when he arrived in Hawaii in 2006, yearning to make a difference in the lives of children in hardscrabble neighborhoods like those on the Waianae Coast.

About an hour’s drive from bustling Honolulu, the stretch of unspoiled beaches and looming mountains is home to a high concentration of Native Hawaiians and some of the state’s lowest-performing schools. So Sager learned their culture, bought a condo and planned to stay.

After seven years, Sager, now 29, quit, packing up this summer for Texas and becoming the latest teacher Hawaii could not keep as it tries to fill a seemingly perpetual teacher shortage. He said he was frustrated by constant educational experimentation.

Now, administrators’ efforts to retain teachers have taken on a new urgency as they try to make progress on promised reforms that won Hawaii a $75 million federal “Race to the Top” grant. Teacher retention is one of the keys to those reforms.

They are offering $1,500 bonuses to work in “hard-to-staff” schools and plan to increase that amount to $3,000 next school year. They are also holding classes in Hawaiian culture and language, and teaming new arrivals with veteran teachers to help ease the transition.

“This is a pretty big push for us,” said Alex Harris, who is overseeing the state education department’s “Race to the Top” efforts involving teachers. “We don’t want to be recruiting at a high volume every year and losing professionals in their second or third year.”

Hawaii — the only state with a single, statewide district — has long had to turn to the mainland because local teacher education programs can’t produce enough graduates to fill classrooms across the islands, especially in remote schools.

Getting the newcomers to stay is difficult, as they face culture shock, a high cost of living and a vast ocean separating them from their families.

“I recruited hundreds of teachers,” said Al Nagasako, who was principal at Nanakuli High and Intermediate School, where Sager taught. “You begin to select the good ones, and you know they’re not going to stay.”

The U.S. Department of Education criticized Hawaii for not doing a good job of publicizing the bonus for teachers to work in “hard-to-staff” schools, so Harris said the bonus has become a more prominent part of the pitch.

A new recruitment perk targets mainland teachers who can fill badly needed special education vacancies by offering them relocation bonuses, Harris said. The highest amount is $6,000 to work in Waianae or the Big Island’s Kau, Keaau and Pahoa areas.

Those areas make up the low-performing, high-poverty schools that “Race to the Top” reforms are focusing on.

After his arrival, Sager, of Warren, Ohio, took a bus tour along with other new teachers and saw the poverty on the Waianae Coast.

Settling in required developing an ear for the pidgin English his students spoke and learning to pronounce vowel-laden names he never heard before. Even as he earned their acceptance, Sager said, he grew frustrated with feeling like he and his students were lab rats for experimental programs.

“We start and it’s not perfect, so we scrap it and start over,” he said.

State education officials are also offering a mentoring program, which began last school year, meant to help teachers feel supported, Harris said.

Nanakuli teacher Dennis Tynan bonded with a group of other teachers who were also adjusting to Hawaii when he arrived 10 years ago.

Tynan, 46, said the group helped him feel connected to the school. He also attributed his longevity to being older when he arrived from Texas, arming him with more life and classroom experiences. Now that he’s one of two left in that group, he’s starting to wonder about his future.

But those doubts are eased by his students, who no longer treat him like an outsider.”
