v.
RHEA COUNTY BOARD OF EDUCATION.
Court of Appeals of Tennessee, Eastern Section, at Knoxville.
February 15, 2005 Session.
April 28, 2005.
Permission to Appeal Denied October 24, 2005.
*164 J. Arnold Fitzgerald, Dayton, Tennessee, for the appellant, Lee Ketchersid.
Robert G. Wheeler, Jr. and Deborah A.G. Smith, Nashville, Tennessee, for the appellee, Rhea County Board of Education.
Permission to Appeal Denied by Supreme Court October 24, 2005.

OPINION
CHARLES D. SUSANO, JR., J., delivered the opinion of the court, in which HERSCHEL P. FRANKS, P.J., and SHARON G. LEE, J., joined.
Lee Ketchersid, a tenured teacher in the Rhea County School System, appealed her dismissal to the Rhea County Board of Education ("the School Board"). Following a hearing, the School Board determined that the evidence supported the charges against Mrs. Ketchersid of insubordination, incompetence, and inefficiency under the Teachers' Tenure Act, Tenn.Code Ann. § 49-5-501, et seq., and voted to terminate Mrs. Ketchersid as a tenured teacher. Mrs. Ketchersid appealed the School Board's decision to the trial court, which, following a de novo review, held that her dismissal was supported by sufficient evidence. Mrs. Ketchersid appeals, arguing that the trial court erred in this determination. We affirm.

I.
During the 2000-2001 school year, Mrs. Ketchersid, who was certified to teach children in grades K-12, was a kindergarten teacher at Graysville Elementary School. Due to her failure to meet the requirements of an improvement plan at Graysville, Mrs. Ketchersid was transferred to Rhea Central Elementary School at the beginning of the 2001-2002 school year and placed in charge of a "Title I" classroom of seven third-grade students. These students were identified as being below their grade level and in need of remedial instruction; the students were not, however, placed in the classroom due to behavioral or discipline problems.
On October 11, 2001, one of Mrs. Ketchersid's students came to assistant principal Buddy Jackson's office in tears, explaining that Mrs. Ketchersid had "smacked her on the face." Assistant Principal Jackson then met with the child and her parents, as well as Mrs. Ketchersid, in an attempt to determine what had happened. The following day, Jackson and Principal Doug Keylon met with Mrs. Ketchersid to discuss *165 her treatment of students. At that time, both Jackson and Keylon stressed to Mrs. Ketchersid the importance of being positive with the children and told her that she was not, under any circumstances, to put her hands on the students.
In February, 2002, another student's parents reported to Principal Keylon that Mrs. Ketchersid had slapped their child. Principal Keylon reported this allegation to Dr. Sue Porter, the Director of Rhea County Schools. On February 12, 2002, Director Porter and Assistant Director Dallas Smith, along with Principal Keylon and Assistant Principal Jackson, interviewed some of the students from Mrs. Ketchersid's classroom on an individual basis. The students informed the administrators that Mrs. Ketchersid would place her hands on their faces when she became angry with them. One student told the group of administrators that Mrs. Ketchersid would often hit him over the head with a soft-cover textbook. More than one student referred to Mrs. Ketchersid having pinched their cheeks when she was angry.
Following these meetings with the students, the administrators brought Mrs. Ketchersid in for a private meeting. When questioned as to whether she had hit students over the head with a book, Mrs. Ketchersid replied that she had done so when she was angry, and she then proceeded to demonstrate by taking a legal pad and tapping Principal Keylon on the head. Mrs. Ketchersid also admitted to placing her hands on the faces of or slapping five out of her seven students. She stated that she did so when she was angry and when the children were being disrespectful. When asked when she had last placed her hands on a student's face, Mrs. Ketchersid admitted that she had done so that very morning. At the conclusion of this meeting with Mrs. Ketchersid, Director Porter informed her that, in light of her "complete insubordination" for failing to follow the directives of Principal Keylon and Assistant Principal Jackson to refrain from placing her hands on the students, she was not to return to her classroom and that she was henceforth suspended without pay.
On March 14, 2002, Director Porter recommended to the School Board that Mrs. Ketchersid be dismissed as a tenured teacher from the Rhea County School System, based upon Mrs. Ketchersid's alleged insubordination, incompetence, inefficiency, and neglect of duty. The School Board then recommended Mrs. Ketchersid's dismissal.
Mrs. Ketchersid requested a hearing before the School Board in order to appeal its decision, which hearing was conducted on July 15, 2002. At the conclusion of the hearing, the School Board determined that the charges of insubordination, incompetence, and inefficiency were supported by the evidence, and the School Board, by a vote of 6 to 2, voted to terminate Mrs. Ketchersid from her tenured position with the Rhea County School System.
Mrs. Ketchersid appealed the School Board's decision to the trial court. After reviewing the record, the trial court found that Mrs. Ketchersid received a fair hearing and that there was sufficient evidence to justify her dismissal. From this judgment, Mrs. Ketchersid appeals.

II.
In this non-jury case, our review is de novo upon the record of the proceedings below; but the record comes to us with a presumption of correctness that we must honor "unless the preponderance of the evidence is otherwise." Tenn. R.App. P. 13(d). The trial court's conclusions of law, however, are accorded no such presumption. Campbell v. Florida Steel Corp., 919 *166 S.W.2d 26, 35 (Tenn.1996); Presley v. Bennett, 860 S.W.2d 857, 859 (Tenn.1993).

IV.
On appeal, Mrs. Ketchersid only asks us to decide whether the trial court erred in its determination that the School Board was justified in dismissing her as a tenured teacher.
The School Board found sufficient evidence to support the charges of insubordination, incompetence, and inefficiency, thereby justifying Mrs. Ketchersid's termination. Insubordination, as defined in Tenn.Code Ann. § 49-5-501(7)(A), includes the "[r]efusal . . . to carry out specific assignments made by . . . the principal." Both Principal Keylon and Assistant Principal Jackson testified before the School Board that they specifically instructed Mrs. Ketchersid, in October of 2001, to refrain from placing her hands on any of her students again. Mrs. Ketchersid testified that it was her understanding of their instructions that she was not to touch the student who made the October complaint, but that the directive did not extend to the other students in the class. However, she did admit that it made sense that they were instructing her not to touch any of the students. When Mrs. Ketchersid was questioned following the February, 2002, complaint, she admitted that she had continued to place her hands on the students' faces, even as recently as that very morning.
There is no question that Mrs. Ketchersid refused to follow a specific directive from Principal Keylon. See Tenn.Code Ann. § 49-5-501(7)(A). We therefore agree with the trial court's finding that "[Mrs.] Ketchersid's refusal to refrain from striking students [is] an insubordinate act as defined by the statute."
The definition of incompetence includes "evident unfitness for service" and possessing a "condition making teacher unfit to instruct or associate with children." Tenn.Code Ann. § 49-5-501(5). Mrs. Ketchersid admitted in the hearing before the School Board that she would place her hands on the children's faces in order to get them to pay attention to her:
OK the smacking [the children] are referring to is when I took hold of their face, to direct their attention to me, because they wouldn't, they would misbehave and not look at me. They weren't looking at me, they weren't paying attention to the lesson, you know they weren't paying attention, so I took their face to look directly at me and then I think a couple of times I did go pat, pat, pat, but they were like punctuation marks. I was telling the child, I was trying to make them understand that I mean business. That they had to obey me.
Director Porter testified that, when Mrs. Ketchersid was questioned by the administrators on February 12, 2002, she complained that her class of students was "just all bad" and she had "nothing but the bad" students. Director Porter explained to Mrs. Ketchersid that the children were *169 placed in her classroom based on their being below grade level and not due to any discipline problems. Mrs. Ketchersid, however, continued to refer to the children as bad and disrespectful, telling Director Porter that she placed her hands on the children's faces "when [she] gets angry and when [the children] are disrespectful."
As Mrs. Ketchersid was certified to teachand had taughtK-8 students for over ten years, it is shocking to this court that she felt it necessary to grab the faces of her third-grade students or hit them over their heads with a book in order to get their attention. Certainly, a teacher with that much experience should be capable of controlling her anger and handling her students in a more professionaland safemanner. Without question, Mrs. Ketchersid's tactics amount to "evident unfitness for service."
There is also sufficient evidence, as found by the trial court, to support a finding of inefficiency, which is defined to include "wanting in effective performance of duties." Tenn.Code Ann. § 49-5-501(6). Assistant Principal Jackson testified before the School Board that, when he had observed Mrs. Ketchersid's classroom prior to her February 12, 2002, suspension, he was forced to call down a child who was misbehaving because Mrs. Ketchersid was doing nothing to control the situation. Jackson stated that he had never had to call down a child before while observing any other classroom. Mrs. Ketchersid even admitted at the hearing that she had failed to appropriately discipline her students and make them behave, in spite of her 24 years of teaching experience. Again, we agree with the trial court's finding that "[Mrs.] Ketchersid's need to resort to such physical tactics, as well as the inability to maintain an orderly classroom, constitutes sufficient evidence of inefficiency and incompetence."
Furthermore, there is ample evidence that the School Board conducted a fair and impartial hearing, dismissing the charge of neglect of duty upon finding that the evidence did not support it. In addition, the School Board, as noted by the trial court, engaged in "extensive discussion and debate as to the appropriate disposition of the case." In light of all of this evidence, we find no error in the trial court's determination that the School Board was justified in dismissing Mrs. Ketchersid.

V.
While Mrs. Ketchersid presents only one issue on appeal, the School Board construes her argument as raisingor attempting to raisetwo additional issues, to which the School Board has chosen to respond. First, the School Board asserts that Mrs. Ketchersid "makes a vague allegation that several provisions of the collective bargaining agreement between the [S]chool [B]oard and the teacher's association were violated in this case." Second, the School Board states that Mrs. Ketchersid "argues that she was `demoted from her job as Kindergarten Teacher at the Graysville Elementary School, prior to there being any charges made against her. . . .'"
With respect to the first issue, our thorough review of the record reveals that at no time did Mrs. Ketchersid raise with the trial court the issue of violations of the collective bargaining agreement. It is well-settled that issues not raised at the trial court level may not be raised for the first time on appeal. Simpson v. Frontier Cmty. Credit Union, 810 S.W.2d 147, 153 (Tenn.1991). However, even if Mrs. Ketchersid had raised this issue belowand we do not believe that she didshe has failed to include a copy of the collective bargaining agreement in the record. Without that document, we are unable to *170 address this purported issue in any event, as there is no proof in the record concerning it.
As to the second issue, there is nothing in the record to indicate that Mrs. Ketchersid ever raised the issue of her "demotion" before the trial court; as such, she is not permitted to raise it now. See Simpson, 810 S.W.2d at 153.

VI.
The judgment of the chancery court is affirmed. This case is remanded for the collection of costs assessed below, pursuant to applicable law. Costs on appeal are taxed to the appellant, Lee Ketchersid.
