After noticing that mostly white lifeguards worked at the public pools used by Latino and African-American kids, the Phoenix aquatics department decided to try to recruit minorities to lifeguard.
On a recruiting effort over the winter at Alhambra High — where more than 90 percent of the students there are black, Latino or Asian — the city's Melissa Boyle tells the students she's not looking for strong swimmers. None of the teens who showed up to hear the pitch is on the school swim team because like many under-resourced schools, Alhambra doesn't have one.
"We will work with you in your swimming abilities," Boyle says.
Boyle's colleague Kelly Martinez takes on the delicate task of explaining to the recruits the scenario the city is trying to correct.
"The kids in the pool are all either Hispanic or black or whatever and every lifeguard is white, and we don't like that. The kids don't relate, there's language issues," Martinez says.
Martinez turns to a Latina student next to her. "Do you speak Spanish?" she asks. "We need more lifeguards who can speak Spanish."
Competitive swimming still has a reputation as a white sport. And a national study released in 2010 found African-Americans and Latinos reported much lower swimming proficiency compared to whites.
"It's that catch-22," says Becky Hulett, who oversees Phoenix's public pools. "If the kids don't learn how to swim, as adults they are not going to swim, they aren't going to take their own kids to swim."
So two years ago, Hulett began rethinking lifeguard recruitment. Traditionally, Phoenix's 500 lifeguards came from more affluent parts of town, most of which are farther from the public pools.
"It really populated from schools that had swim teams, and so that was our feeder into our lifeguarding programs," Hulett says.
To help diversify its lifeguard ranks, the city raised about $15,000 over the past two years in scholarships to offset the cost of lifeguard certification courses. Recruits who pass a swim test at the end can apply to be city lifeguards.
As the teens swim laps at Alhambra, it's clear many haven't had much formal training. But the coaches of the course aren't fazed and are prepared to put in the time to teach.
"Honestly, I have a little bit a fear of the water, and I wanted to overcome that fear," says high school junior Jesus Jimenez. Jimenez didn't grow up going to pools with his family but likes the idea of lifeguarding.
"It is nice to have the satisfaction of knowing that if somebody is in trouble you can save them at any time," he says.
If Jimenez is selected to be a lifeguard, other pool staff will work with him on his swimming skills all summer.
