Favorite Scripture
“Therefore, we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day.

For what is seen is temporary, but what is unseen is eternal.”

Leif Johnston
Athletic Director/Head Football Coach
Favorite Scripture
Be on your guard; stand firm in the faith; be courageous; be strong. Do everything in
love.
1 Corinthians 16:13-14
Coach Johnston is entering his seventh year at Central Texas Christian School. He previously served as the
Head Basketball Coach and Football Offensive Coordinator. He attended the University of Mary Hardin-Baylor.
While there Coach Johnston played football as well as spending time as a student-assistant for the
basketball program.
Leif is married to his wife Morgan, and they have one beautiful daughter, Lennon. He is thankful to God for
their support in understanding the time and energy that goes into transformational coaching. Athletics has
been an integral part of Coach Johnston’s life, and has taught him many lessons that may have otherwise gone
unlearned. He truly believes that what is learned on the field, court, diamond or track directly relates to
the adversity that each young person will ultimately face in their lives. “We merely want to use athletics
as an avenue in giving them tools to handle adversity in a way that Glorifies Christ,” says Coach Johnston.
CTCS Athletics strives to compete with honor as we represent Christ first and foremost. Having the
opportunity to further His Kingdom by the way we act, talk, and perform is the most satisfying aspect of
what it means to be a coach.

School Board
Central Texas Christian School Board Governance Model
Central Texas Christian School is a 501(c)(3) non-profit organization, existing to provide Christian education. As such, the CTCS School Board operates using a non-profit form of governance rather than the form of governance used by public schools, which are political bodies subject to open meeting requirements. The Board follows principles of policy governance, whereby the Board sets broad policies within which the school is to operate, but does not interject itself into the operations of the school. No individual board member has any authority over school personnel or operations, nor does any individual board member have authority to speak for the school. The Board believes in the one-voice authority of the Head of School, who is accountable to the entire Board, not to any individual board member.
Board Meetings
Central Texas Christian School does not hold open meetings. The Board concerns itself with school policy and strategic planning rather than with daily operations. Therefore, curriculum, personnel and student policies are primarily determined by the Head of School with assistance from the administrative team and other staff members, subject to parameters set forth in Board policies.
Board Member Selection and Qualifications
The Board is self-perpetuating. All potential Board members must be nominated from within the Board, although names may be suggested for consideration by anyone. Members of the Board must be born-again believers and subscribe without reservation to the school’s Statement of Faith and Statement of Educational Philosophy. Members of the Board must be Christian role models in the school and community and members in good standing of a local evangelical church whose doctrine is consistent with the school’s Statement of Faith.
