Principal's Message

Thomas Mitchell, Principal
Welcome Colony Titans to a school year none like any other. The beginning of this school year will go down in history as the first, fully virtual distance learning model ever created. At 12:00pm on Wednesday, August 5th the bell rang for staff to begin delivery of virtual instruction and for students to begin engaging in what will be our new (temporary) norm. With safety as our number one goal we have prepared the campus for all Colony staff to return to begin the process of the Distance Learning Model.
 
I want to thank our students and parents for the patience and cooperation shown during the registration process. Last spring the class of 2020 graduated in what was called our “Colony High School 2K20 Graduation Parade.” This summer we employed the same strategy and registered over 2,000 students over a 6-day period. It is not the ideal method of meeting new students, but it does allow for a hedge of protection for all.
 
I am so happy to announce that even though we had to close school down in emergency fashion last spring the Titans did not falter in the area of student achievement. At the beginning of the 2019-2020 academic year Colony High School set goals in four (Big 4) different areas. One of the areas has to do with CAASPP Testing, which was suspended due to closure of schools across the state. The other 3: Percentage of students qualifying for Free & Reduced Meal Program (FRMP), A-G Rate, and lowering the percentage of Freshman earning 45 or fewer credits remained in our sites all year. I am proud to announce we met the FRMP goal, raised our A-G percentage to 71.72% and decreased the percentage of Freshman earning 45 or fewer credits to 6.8%. This is considered tremendous work, especially under the stress of a pandemic.
 
Knowing you have choice, when it comes to enrolling your student, I am pleased you have chosen Colony High School. As your Principal, I promise we will work hard at improving in every facet. Even though we may be learning from a distance that does not mean we cannot become more united. We will address issues relative to equity and cultural proficiency and work for change so all students, especially those of color, can feel more connected to their academic community.
 
I look forward to the day we can all be together again in a safe, pandemic free environment, where students are roaming the halls and enjoying the camaraderie of their high school. The Titan, as a mythical god, stood above all and was revered by all-We should be a proud community. I believe this year’s Colony Titans will Rise to the occasion and make this school year, no matter the circumstances, one of the best school years ever.
 
Proud to be a Titan,
 
Mr. Mitchell
