Jackson played at one of the local high schools down the road from the University of Miami, Booker T Washington. While there, he played primarily as a defensive end and racked up gaudy stats as a senior. In his graduating year (2014), he ended the season with 68 tackles, 12 sacks and 13 more QB hurries to boot. During his senior year he was able to earn the Florida 4A State Championship title. Jackson had offers from Arkansas, West Virginia, Louisville and Texas but decided to sign his letter of intent to Miami.
