Rex Putnam is the only North Clackamas high school that houses the IB Programme.

Colleges and Universities around the world recognize the IB Programme and it is a very high honor to complete it.

Of 306 students, 249 graduated, 31 dropped out, 11 received a modified diploma, and 15 were still in high school the following year.

In March 2024, Rex Putnam's Boys Varsity Basketball team made school program history after winning 52-42 in a state playoff game against South Albany High School, bumping their record to 21-4, the best record seen since 1964.
