Kayla Mahalchak never lived in a world without running water or electricity. The only bumps on her ride to school are potholes along a paved road, rather than a rickety dirt road.

Thanks to her graduation project at Chartiers Valley Senior High School, she has seen the other side -- and it's changed her life. A whirlwind nine days in Nyadire, Zimbabwe, as part of her graduation project opened her eyes to what her future holds.

"At first I was very nervous and didn't know what to expect, but once I got there, I just fell in love with the people. They made me feel at home," said Kayla, 17, of Heidelberg. "It's so much work, but I can say (the graduation project) did help me develop as a person. It really does help prepare you for your college experience."

Graduation projects in Pennsylvania take on many forms, ranging from a one-page paper to a substantial service project and presentation. The Pennsylvania Department of Education (PDE) implemented the mandated project for the 2002-03 school year. According to the PDE's standards, students must be able to "apply, analyze, synthesize and evaluate information and communicate significant knowledge and understanding" through their projects. The department set those standards to give districts freedom with the project, said Leah Harris, PDE assistant press secretary.

Generally, graduation projects fall into one of three categories -- service, academic or career-oriented. Most districts require both a written and oral component to the project, whether it is a research paper or a physical project.

That's important, said Daniel Paul, a certified vocational evaluator for the Allegheny Intermediate Unit. Paul, who works with students developing graduation projects throughout the county, said one of the most important aspects of the projects is the rigor.

"Learning takes place everywhere, not just in those four walls," Paul said. "Learning takes place every day. They need to be challenged."

Some projects -- such as Kayla's -- are all about service. Local districts require anywhere from 10 to 30 hours of community service as part of service intensive projects. At North Hills School District -- where the project was recently altered from a three-part, intensive project to a one-page paper on the topic of the student's choice -- students used to be required to complete 50 hours of community service if they chose a service-based physical project. Doug Sundo, president of the North Hills Education Association, said 40 percent of students during the past two school years focused on volunteer-based projects, totaling more than 17,000 hours of community service in the North Hills.

At Chartiers Valley, Kayla dedicated her senior project to helping the Nyadire Connection, which benefits a mission in Africa housing a hospital and schools. With career aspirations in medicine, Kayla had initially planned to focus her project on infectious disease control in Third World countries. Now, the fundraiser event she has planned for April will benefit all of the people on the mission.

"This definitely developed into something different than I had anticipated," she said. "I can say it did help me get into college."

That's one objective of graduation projects. No matter what the topic of the project, Paul said, students should exhibit four capabilities that will be necessary in college or the workforce upon completion -- communication, technology, problem-solving and community activity.

"These are important life skills they're developing," Paul said. "And these projects can be integrated into academics."

That's what many districts choose to do. At Penn Hills School District, students are required to complete a language arts project, the intensity of which is based on the level of English the student is enrolled in, said Casey Reynolds, co-chair of Penn Hills Senior High School English department.

"The focus is not on citizenship, but on research skills, writing, formatting, Modern Language Association style, media research and other skills students will need in their varying post-graduation endeavors," Reynolds said.

Post-graduation is another intense focus of these projects. Career-planning continues to begin earlier and earlier in area school districts, Paul said. For instance, in the Plum School District, students focus on a profession they are interested in pursuing, including a job-shadowing experience and reflection, said spokeswoman Dawn Check.

"We're looking to prepare these young people to go out and find their future," Paul said. "So it shouldn't be 'who will hire me,' but 'where can I go to get the skills.'"

Lynne Taiclet's eldest son, Scott Winter, had reconstructed a vintage car for his senior project at North Hills.

"The average senior project, the way they used to be, would be probably very similar to what you do in a job today to give a presentation in a meeting," said Taiclet, 48, of Ross. "That type of project is not so different from what many people do on a daily or weekly basis, depending on their job."

Whether it is honing writing and presenting skills in preparation for college or changing a student's perspective on daily life, graduation projects can have a profound effect on teens -- at least it did for Kayla.

"It taught me that I needed to be patient and open to other people and how they live their lives," Kayla said. "I wanted to help everyone. And now I know how I can at least start. I never would have been so sure about my future if it wasn't for my graduation project."
