On February 4, 2019, students from the Senior High School Department celebrated their first Organizational Day themed: "Unity Across Disciplines". Senior High School is the additional two years of education instated by the Philippines' K to 12 education program. In these additional two years students are free to specialize in strands which may better prepare them for their future pursuits.
Currently, DCHS offers all four (4) pre-college academic tracks accredited by DepEd. Students may choose from either STEM (Science, Technology, Engineering & Math), ABM (Accountancy, Business, & Management), HUMSS (Humanities & Social Sciences), or GA (General Academic) to help equip themselves for their college degrees. Senior High is currently offered in the V. Mapa Campus. In Davao Christian High School, the STEM strand is further subdivided into two (2) more strands: STEM-SCI, which focuses on Biology and STEM-ENG which focuses on Engineering.
The whole day event consisted of programs including a booth promotion for each strand directed to the Grades 9 and 10 students, a mini-Sportsfest with each strand battling it out for wins in basketball, volleyball, and captain ball, as well as a trivia contest for each strand.
