delivered the opinion of the Court.
Relators, citizens of Cannon county, seek by mandamus to compel the county board of education “to institute and maintain at Woodbury public high school, a first-class high school for the period of nine months each year and to employ teachers and do all things necessary *212for the maintenance of the school, and to prevent the appropriation by the board of school funds to the prejudice of this school.”
The petition recites that there is a commodious steam-heated brick school building at Woodbury suitable for the purpose, and that this place has been designated by the educational department as the only first-class high school in the county.
The county court levies a tax of fifteen cents on the dollar for high school purposes, and the petition recites that from the proceeds of this levy, and supplementary aid from the State, a first-class high school can be maintained, but that contrary to the provisions of chapter 40, Acts of 1921, the revenue derived from the levy for high school purposes is distributed among seven schools throughout the county, reducing the school term to three and one-half months each year.
Respondents, by appropriate answer, made return of the alternative writ, and say it would be ruinous to the high school interests of Cannon county to devote practically all the high school funds to the maintenance of one school, and deprive other sections of high school advantages; that the topography is such that many sections cannot patronize the school at Woodbury, and this, together with the location of highways and the distribution of population, makes it impractical to locate a single school, and that they are maintaining schools to serve the best interests of the county.
Respondents say, however, if but one school is to be maintained, the county board of education is the only agency authorized by law to designate its location, and that *213the court cannot properly compel the board to exercise a discretion lodged in them by statute.
Relators insist that chapter 40, Acts of 1921, is mandatory, and by its provisions the county board of education must establish a first-class high school in the county and maintain it, and, having failed to observe the statute, that relators may, under the facts recited in the petition and disclosed in proof, compel the board to locate the school at Woodbury to the exclusion of any other place in the county.
In the promotion of the State’s educational, policy, the legislature has created local agencies in each county, charged with the duty, and clothed with the discretion, of administering the school system. , The limitation upon their power is and has always been obedience to the law, observance of good faith, and an honest exercise of discretion.
In the incipiency State academies were created, which under the statute were managed by trustees of the locality, and when the primary system was adopted, three school directors Avere provided for each district, culminating in the county board of education as provided in chapter 120, Acts of 1921.
By subsection 2, section 5, of the act, power is conferred upon the board of education to administer the system within the county. Until recently it lay in the discretion of the county courts and the local school authorities to determine whether or not a high school should be established, but by chapter 40, Acts of 1921, the legislature makes it obligatory upon the counties to maintain within their borders at least one first-class high school, to *214be located where the greatest number of high school pupils may be benefited.
The validity of the act is questioned by respondents upon the ground that it is vicious cláss legislation. The act provides for the establishment of a high school in each county, and applies to all counties alike, and, being impartial in its provisions, and in the manner of its application, we are unable to see that it violates article 11, section 8,- of the Constitution, as insisted upon by the respondents.
The act being valid, it is incumbent upon the county board of education to make a reasonable effort to observe its requirements, using the means provided by the county and State financial agencies to effectuate that purpose.
The act declares it a part of the State’s educational policy that there shall be at least one first-class high school in each county, and that the terms be uniform throughout the State. In the establishment of such schools, the several county boards of education are given authority to select the location and direct their operation. Chapter 120, Acts of 1921; chapter 40, Acts of 1921; State ex rel. v. Board of Education, 122 Tenn., 162, 121 S. W., 499; Cross v. Fisher, 132 Tenn., 31, 177 S. W., 43, Ann. Cas., 1916E, 1092; and Walker v. Monger, 6 App. Cas., 261.
The board may maintain more than one high school in the county, but under the act they must, according to the resources' at their command, locate and maintain one first-class high school as therein provided. Chapter 40, section 1, Acts 1921. In the exercise of its mandatory processes, the judicial department must recognize the discretionary powers of local agencies charged with administering the *215school system oí the counties, to assure, if for no other reason, harmonious co-operation between the State and counties, and between the school officers and the patrons of the school. That is necessary to the success of the school system.
The matter of locating the school in Cannon county has not been presented to the hoard in the form of a demand that they observe the law and exercise their sound discretion, but has been presented only in the form of a demand that they locate the school at Woodbury.
In the opinion expressed by the witnesses, Woodbury is the proper location, and the trial judge so found, and if that location meets all the requirements of the act, and would benefit the most high school pupils, it would, of course, become the duty of the board to locate the school there. But relators do not establish a clear legal right to coerce the board of education in the selection of the site. The discretion is lodged in the board, and they should be given an opportunity to exercise their sound discretion. Given such an opportunity, if they refuse to act, or act unreasonably or capriciously, the writ would lie to control their action and-compel obedience to the statute.
Upon the facts as presented in this proceeding, the writ should have been denied. Wherefore the judgment of the trial court is reversed, Relators will pay the costs.-
