It's summer vacation, but these students are training for summer jobs.
"This is often times a student's first opportunity of being in a job," said Michelle Lapis, program coordinator of the Mayor's Youth Employment Program.
Through the Mayor's Youth Employment Program, 75 high school students and graduates will intern with local companies.
"I love it a lot. It works on team building and communication and learning leadership skills," said Daniel McArthur, who is attending Cornell University in the fall.
"How to actually be in a job that's not just school has definitely given me skills I can take with me," said Erin Manning, who is attending Northwestern University in the fall.
Students who returned to the program, say it's been a big help.
"Working with Mayor's Youth gave me the attitude to put myself out there and try to get a job. So I worked as an SAT tutor this fall and winter," said Manning.
"I'm currently working at A&P Supermarket on High Ridge. I think it's taught me to be more professional and I have more respect of where I am," said Joseph McIntosh.
"Learning what their critical thinking skills are and getting that feedback that are going to help them be more competitive down the road," said Lapis.
Of the businesses involved this year is Starwood Hotels. Which is taking on 20 students, in partnership with Sacred Heart University.
The program will kick off with an opening ceremony Thursday evening. Students begin their internships next week.
