Accountability rating
Based on the accountability ratings released by the Texas Education Agency on August 2, 2007, PSJA High is currently rated "Academically Acceptable". The school has received a TEA Recognized Campus status as of 2008.
In May 2010, Gov. Rick Perry visited PSJA High and announced PSJA ISD had been awarded a $2 million All Students: College Ready, College Connected grant through the Texas Education Agency. Perry said, “The Pharr-San Juan-Alamo school district is part of a larger effort across the state to continue improving the quality of a Texas education and ensure every student graduates ready for college or career.” The school district will receive $1.1 million for the first year of the grant, with $2 million total awarded over the next two years, allowing the district to expand its successful early college high school program to the entire district, while combining it with a focused STEM education. Through this grant, more than 60 percent of the 8,000 PSJA ISD high school students will experience college-for-all accelerated programs by the 2013–2014 school year, and at least 30 percent of the 1,600 middle school students will be in accelerated programs. In 2007, the FBI raided school board offices and issued 22 counts of conspiracy and extortion amid allegations that several members of the board received sex, paid vacations, monetary gifts, repairs to their homes, clothing, rifles, and sports tickets in exchange for repeatedly handing valuable school contracts to area construction firms, some of whom also had charges levied against them. Pharr-San Juan-Alamo school board member Rogelio "Little Roy" Rodriguez resigned his seat on the board, before pleading guilty to a federal conspiracy charge.
