PER CURIAM.
The question on appeal is whether the trial court erred in denying plaintiff Golonka's motion for summary judgment, the practical effect of which was to deny her request for a writ of mandamus which would have compelled the Michigan *30 Department of Education to certify her as a teacher consultant.[1]
Plaintiff Golonka, certified by the State Board of Education as a general education teacher and a special education teacher, taught in the South Redford School District. As stipulated to by the parties, for more than ten years she has taught handicapped students with learning disabilities, who have been mainstreamed[2] with nonhandicapped students. She had not, however, completed at least one year of teaching experience in a special education classroom as a special education teacher. Because of her impending layoff as a general education teacher, she and the South Redford School District sought to determine whether the State Board of Education would approve her as a teacher consultant under Rule 340.1790, 1979 AC R 340.1790.
*31 Rule 340.1790 was promulgated by the State Board of Education pursuant to its authority under the special education code and provides as follows:
"Rule 90. A teacher consultant for special education programs and services shall meet the following requirements for full approval by the state board of education:
"(a) Full approval by the state board of education as a teacher in 1 or more areas of special education.
"(b) A minimum of 3 years of satisfactory teaching experience, including at least 1 year of experience teaching handicapped pupils.
"(c) Recommendation to the department, by letter, by the employing superintendent or his designee for approval as a teacher consultant. Evidence of experience and training shall be submitted with the request for approval." (Emphasis added.)
A representative from the South Redford School District sent a letter to the State Department of Education seeking its response to the following inquiry.
"Two of our laid off teachers are fully certified by the state board of education in one or more areas of special education. Although neither teacher has taught in a selfcontained classroom, both have taught many identified handicapped students that have been mainstreamed in their classrooms. Does their work with mainstreamed students qualify them for teacher consultant approval?"
The State Department's response was that "[a] person must have worked in a special education classroom as a special education teacher." In reliance upon this response, the South Redford School District refused to assign plaintiff Golonka to a position as a teacher consultant. She then began *32 direct correspondence with the State Department of Education. The defendant department interpreted the phrase "at least 1 year of experience teaching handicapped pupils" to mean that a teacher consultant must have at least one year of experience teaching handicapped people in a selfcontained, special education classroom. Therefore, the department argued, even though plaintiff Golonka had taught handicapped students who had been mainstreamed into her general education classroom, she was not certifiable as a teacher consultant because she had not spent at least one year teaching handicapped students in a self-contained, special education classroom.
On August 28, 1979, plaintiff Golonka filed a complaint seeking a writ of mandamus to compel defendants to certify her as a teacher consultant under Rule 340.1790. In response to an order to show cause issued by the trial judge, the defendant Department of Education argued that the writ should be denied since, according to its interpretation of Rule 340.1790, plaintiff Golonka did not meet the requirements necessary to be a certified teacher consultant.
On December 10, 1979, plaintiffs filed a motion for summary judgment in which they claimed that defendants had failed to set forth a valid defense, GCR 1963, 117.2(2), and that there were no genuine issues of material fact, GCR 1963, 117.2(3). At a subsequent hearing held on this motion wherein both parties stipulated that there were no genuine issues of material fact, the trial court denied plaintiffs' motion and instead granted summary judgment in favor of defendants. Plaintiffs appeal as of right.
We note at the outset that had the trial court granted plaintiffs' motion for summary judgment, it would have been issuing mandamus.
*33 The issuing of writs of mandamus is discretionary with the trial judge, and an appellate court will not disturb the trial court's ruling absent an abuse of discretion. Carlson v City of Troy, 90 Mich App 543, 547; 282 NW2d 387 (1979). In order for a writ of mandamus to be issued, a plaintiff must have a clear legal right to performance of the specific duties sought to be compelled. Id. The trial judge was not convinced that plaintiffs were entitled to mandamus as a matter of law and suggested that plaintiffs move for a declaratory judgment rather than for summary judgment. When plaintiffs persisted with their motion for summary judgment, the trial court denied it on the ground that plaintiffs were not entitled to mandamus.
The trial judge took the position that he should defer to the administrative expertise of the Department of Education and that he should not substitute his judgment for the department's. He also concluded that the interpretation placed on Rule 340.1790 by the department was reasonable when read in conjunction with the entire special education code.
The Supreme Court recently reaffirmed its position that the courts should pay some deference to interpretive rulings made by those charged with the duty of executing statutory grants of power.
"`The construction given to a statute by those charged with the duty of executing it is always entitled to the most respectful consideration and ought not to be overruled without cogent reasons.'" Board of Education of Oakland Schools v Superintendent of Public Instruction, 401 Mich 37, 41; 257 NW2d 73 (1977), citing United States v Moore, 95 US 760, 763; 24 L Ed 588, 589 (1877).
*34 We believe this principle should be afforded at least equal, if not greater, weight in the context of administrative interpretations of departmental rules. Having reviewed the record and briefs, we concur with the trial judge's conclusion that the State Department of Education's interpretation of the rule in question is reasonable when considered in light of the entire special education code.
Since the interpretation placed on Rule 340.1790 is reasonable, plaintiff Golonka has no clear legal right to be promoted to the status of teacher consultant. Since the record contains evidence to support the trial court's denial of mandamus, we may not disturb its decision. South Looking Glass Drainage Dist Board v Grand Trunk W R Co, 357 Mich 215, 222; 98 NW2d 543 (1959). We find no error in its grant of summary judgment for the defendants.
Affirmed.
