Murray High School is one of the schools in Utah piloting the Utah State Office of Education U-PASS & criterion-referenced tests (CRTs) online. The school has received $100,000 to purchase new laptops and upgrade current computers. The administration of Spring 2008 criterion-referenced tests (CRTs) through computer-based testing (CBT) was performed through Pearson's assessment systems.

At the beginning of 2007-2008, administrators and Murray High School's Environmental Club started a program to save energy and money. Adjustments at the school, and other schools and offices in the district, included changes to the thermostats and turning off running water in the restrooms and unplugging machines during weekends and long breaks. This has caused difficulties for the instrumental music programs at Murray High since instruments can sustain harm when temperatures are allowed to drop drastically over long school breaks. Recycling bins have been placed throughout the school. Students are sent to detention if they are found to have wasted excessive amounts of water. Since its beginnings, the district has saved $405,000, all of which went into teachers' budgets. It was projected that the district will have saved one million dollars or a twenty percent savings per month by the year 2024.

In 2004, Murray High School prohibited same-sex students from participating in the promenade of their prom. Press coverage noted the similarity to Aaron Fricke vs. Richard B. Lynch, a landmark case in high school student LGBT rights. Using Fricke as a precedent, the ACLU threatened to sue the high school on behalf of its gay and lesbian students. The high school reversed its policy and allowed a 17-year-old lesbian student to dance with her girlfriend at the prom.

Another recent controversy was when some students passed around "white privilege cards".
