The Carroll ISD board of trustees approved an agreement at its July 22 meeting that would allow local students to attend Serenity High School in McKinney ISD. “Serenity High exists for adolescents returning from recognized substance abuse treatment centers who are committed to obtaining a high school diploma in a safe [and] supportive, chemical-free environment,” the school’s mission statement reads. This would offer eligible students another option for how to complete their high school education, according to CISD meeting documents. Serenity High also serves students from several other districts, including Plano ISD, Frisco ISD and Lewisville ISD. Serenity High helps provide smoother transitions from treatment programs to school settings, according to the school's website. The school also features recovery support meetings; low student-to-teacher ratios; individualized counseling for school, personal and social development; community service projects; mentoring by staff; peer support groups; and team-building events. The cost per student totals $85 per day for the actual number of days each student is enrolled in the program, and it will be divided between the school district and the students’ families, according to meeting documents. CISD would pay $33 per day per student, and parents would pay $52 per day. Those who opt for this program will still be considered CISD students, as Serenity High will send grades and attendance records to CISD. The proposed agreement to allow for the program passed with a 4-0 vote. CISD board members Michelle Moore, Todd Carlton and Bradley Taylor were absent at the meeting.
