Carol was born in Ganado, Texas along with a twin sister, Cheryl to Jonathan and Serelda Knoerschild Sappington. She began school in 1969 at Vanderbilt Elementary and her educational adventure continues to this day. In 1974 she transitioned to sixth grade to become a Rattler at Industrial Junior High School in Lolita. Her father taught her seventh grade math and built the foundation for her future career. In 1977 she entered High School at Industrial High School in Vanderbilt where her mother taught her English and instilled a love of learning. She enjoyed participating in athletics, band, F.T.A., N.H.S., and Student Council, while receiving superior academic instruction from outstanding teachers in the advanced classes. Carol graduated as salutatorian and Cheryl as valedictorian in 1981. Higher education began at The University of Texas at Austin where Carol was a member of the Longhorn Band. She graduated with honors in 1985 with a Bachelor of Science degree with teaching certificates in both mathematics and physical science.

    Carol began her teaching career at Crockett High School in Austin, Texas where she taught Algebra and Geometry. She then taught Computer Mathematics and Algebra for five years for Freer I.S.D. In 1990 she accepted a position with her alma mater and returned to Industrial High School as a high school mathematics teacher. Since coming "back home" to Industrial, she received a teaching certificate in physics and her master's degree, a Master of Arts in Interdisciplinary Studies with concentrations in mathematics and computer science. She continues her education by attending conferences and taking graduate classes when possible. Currently she sponsors the I.H.S. T.A.F.E., the Seniors of 2021, and U.I.L. Current Events and Issues team.  This year marks Carol's thirty-fourth year as a high school math teacher.

    Carol is proud to continue the family tradition of being a teacher. Her grandfather the Reverend Ewald Knoerschild taught the students enrolled in the school for the Koop and Casa Blanca Communities. Her grandmother Louise Koop Knoerschild urged the school board to start a music education program for students in the community and the seed for the Golden Cobra Band was planted.  Both parents were employed by the Industrial Independent School District for a combined total of sixty-seven years of service.  Her husband and son are also both certified teachers.

    Carol is married to Kerry Oniel Griffith, a 1978 Industrial High School graduate and current science teacher at Industrial Junior High School. They are the proud parents of four children: Kyle, Kelly, Kylann, and Connor. In November of 2000, tragedy struck and a house fire claimed the lives of her beloved parents and precious Kelly. Only with the tremendous love, support, encouragement, and prayers of family, friends, colleagues and students has this ordeal been survived. Carol's life abounds with countless blessings.
