King Student Earns Perfect Score in AP Computer Science

Clare not only received the top score of 5 but was also one of only 356 students in the world to earn every point possible on the AP Computer Science A Exam, receiving the maximum score on each portion of the exam.

Design Thinking Provides Solutions to Real-World Issues

Upper School students built a three-dimensional model city made of buildings and vehicles designed to address real-world issues. “To begin the project, students were prompted to empathize with a cause or community and ask themselves, ‘who do I want to help and what do they need?’ Once they have defined a problem they would like to solve, they began formulating ideas for how the design of their prototype might provide a solution to that problem,” said art and design teacher Naomi Clark. This process is known as design thinking.
