[¶ 1] John, Carol and Helen Sides appeal the disapproval of their petitions for a minor school boundary change. We affirm.
FACTS AND PROCEDURAL HISTORY
[¶ 2] John Sides, his wife Carol and his mother Helen Sides all filed separate petitions for a minor boundary change transferring their property from the Oelrichs School District to the Hot Springs School District. All three petitioners live together on a Fall River County ranch, and their address is Smithwick, South Dakota. They represent 100 percent of the voters within the proposed boundary change area. There is no question that the amount of land involved implicates the minor boundary change provision of statute.1 The ranch is not coterminous with both school districts, but is separated from the school district line only by federal grassland and state land, all of which is leased by the *910Sides.2
[¶ 3] The Sides children, Amanda (8th grade), Jack (6th grade) and Shauna (3rd grade) attended the Smithwick school, which is in the Oelrichs District, until it closed at the end of the 1994-95 school year. The Sides children were the only students at Smithwick for part of the school’s final year. It is the closing of the Smithwick school which appears to have prompted the petitions for boundary change. The Sides want their children to attend school in the Hot Springs District.
[¶4.] The Sides’ petitions were approved by the Hot Springs District, but unanimously disapproved by the Oelrichs District. The Sides appealed the Oelrichs School Board’s decision to the Secretary of Education and Cultural Affairs as provided by SDCL 13-6-85. After an evidentiary hearing before a hearing examiner,3 the Secretary of Education reversed the school board and approved the petitions. The Sides children were enrolled in the Hot Springs School District, and are presently attending school within that district.
[¶ 5.] The Oelrichs School District appealed to the circuit court, which held a full evidentiary hearing.4 During the hearing, the court required counsel to clearly identify which testimony had been presented to the school board and which testimony was being presented for the first time to the court. At the conclusion of the hearing, the judge ruled from the bench that considering the evidence both ways, the school board decision must be upheld. The Sides appeal.5
LEGAL ANALYSIS
[¶ 6.] Whether the Oelrich’s School Board decision to disapprove the Side’s minor boundary change petitions was clearly erroneous, arbitrary, capricious or an abuse of discretion?
[¶ 7.] A school board’s decision on a minor boundary petition has two avenues of appeal: directly to the circuit court, or to the Secretary of Education. SDCL 13-6-85. The grant of decision-making power to the Secretary is designed to encourage settlement of boundary disputes without resort to court action; however, the decision of the Secretary nonetheless is subject to appeal to the circuit court. The Secretary’s decision in such appeals is to be given no deference by the reviewing court. SDCL 13-8-85; Oldham-Ramona Sch. Dist. v. Ust, 502 N.W.2d 574, 579 (S.D.1993).
[¶ 8.] The circuit court reviews the decision of the school board de novo. SDCL 13-46-6. It is not a trial de novo in the truest sense of the term, and the court is not permitted to determine the propriety of the board’s decision. Strain v. Rapid City Sch. Bd., 447 N.W.2d 332, 338 (S.D.1989).
School boards are creatures of the legislature and are a part of the legislative branch of government. Therefore, the judiciary may not invade the province of the school board’s decision making unless such decision making is done contrary to law.
Moran v. Rapid City Area Sch. Dist., 281 N.W.2d 595, 598 (S.D.1979).
*911[¶ 9.] We are not bound by a presumption that the circuit court decided correctly. The proper scope of review for this court is the same as that of the circuit court. Strain, 447 N.W.2d at 338.
[T]he trial de novo required by SDCL 13-46-6 permits an independent inquiry into the facts, but only for the purpose of passing on the legality of board’s decision. The circuit court must determine (1) whether the board possessed the administrative power to make the decision ..., and (2) whether the board acted unreasonably or arbitrarily, or whether the board manifestly abused its discretion.
Colman-Egan Sch. Dist. No. 50-5 v. Jones, 520 N.W.2d 890, 892 (S.D.1994) (citing Moran, 281 N.W.2d at 599).
[¶ 10.] In the instant case, the school board’s administrative power to make the decision is not at issue; however, in deciding whether the board’s decision was arbitrary, capricious or an abuse of discretion, the circuit court is required to determine only whether there was substantial evidence to support the school board’s decision. Oldham-Ramona, 502 N.W.2d at 580-81; it does not need to justify the school board’s decision by a preponderance of the evidence received. Id. at 579. Substantial evidence has been defined as “such relevant and competent evidence as a reasonable mind might accept as adequate to support a conclusion.” Id. at 581.
[¶ 11.] Keeping in mind this very narrow scope of review, this Court previously has looked to five substantive factors in reviewing minor boundary change decisions:
1. Whether the petitioners are more closely aligned to the economic, social and religious life of the community into which they are being transferred?
2. Whether there is bus service to the residence?
3. Whether the district line which places their property in the current district was drawn in an arbitrary fashion?
4. Whether petitioner’s child has special needs best met in the District petitioners are attempting to join?
5. Whether the petitioners live closer to the school district they are joining as opposed to the district they are leaving?
Colman-Egan, 520 N.W.2d at 892; Oldham-Ramona, 502 N.W.2d at 581.
[¶ 12.] These factors were included in a packet of information provided to the Oel-richs School Board by its attorney prior to the decision of the board on the Sides’ petitions. The school board, in disapproving the petitions, gave the following reasons in the unapproved minutes of its March 13, 1995 meeting:
The John Sides’ petition to move approximately 52 sections of deeded and Buffalo Gap National Grasslands from the Oelrichs School District to the Hot Springs School District was discussed. Carol Sides presented concerns in education, competition, sports and social activities at Oelrichs School. Tom White represented the Pioneer Cooperative Grazing District directors who voted to oppose the transfer of land to the Hot Springs School District. Mileage from the Sides home to both Hot Springs (28 miles) and Oelrichs (20 miles) [sic] was discussed. The education at Oel-richs School is comparable to the education at Hot Springs School. Massive amounts of land would be transferred which would mean a loss to the Oelrichs School in federal monies. A motion was made by Dryden seconded by Trent that in light of the discussion in regards to the Sides Petition, the Oelrichs School District denies the boundary change. Motion carried.
[¶ 13.] The circuit court weighed all five factors in light of the testimony presented before the school board and again in light of the additional testimony presented to the court at its evidentiary hearing.6 The circuit court found substantial evidence to support the school board’s decision either way.
*912[¶ 14.] We consider the five factors reviewed by the circuit court in light of all the evidence presented to it:
[¶ 15.] 1. Whether the petitioners are more closely aligned to the economic, social and religious life of the community into which they are being transferred?
[¶ 16.] The Sides argued that their family is more closely aligned to the Hot Springs community than the Oelrichs community. They point out that they do their grocery shopping in the Hot Springs rather than the Oelrichs, and that they use Hot Springs for legal, medical, and government services. If we were to adopt this logic, however, it would appear that no one is closely aligned to the Oelrichs District. As the circuit court found:
[I]t is not unusual for many Oelrichs School District residents to go to Hot Springs for county services, health care, legal services, dental care, accounting services and veterinarian services. In fact, most residents probably leave the Oelrichs School District for these and many other things. Oelrichs is not a county seat. There is not a doctor in Oelrichs. There are no lawyers ... dentist ... accountant ... veterinarian ... bank ... government offices in Oelrichs.
[¶ 17.] The Sides claim they have closer ties to the Hot Springs District because that is where they attend church, pick up their mail, have their machinery repaired and where Mr. Sides participates in volunteer firefighting activities. This argument is flawed. While these activities may occur in the Hot Springs District, they actually are conducted at Smithwick, which by the Sides’ own admission is divided between the two School Districts. In fact, the church the Sides attend in Smithwick is only 120 feet from the Oelrichs School District boundary. We agree with the circuit court on this factor.
[¶ 18.] 2. Whether there is bus service to the residence?
[¶ 19.] The evidence indicates that neither the Oelrichs School District nor the Hot Springs School District will provide bus service to the Sides children from their home. The Sides ranch is a 36-mile round trip to Oelrichs and a 56-mile round trip to Hot Springs. The Hot Springs District does have a bus which would pick the Sides children up at Smithwick, which would require the Sides to drive 21 miles round trip to drop off their children for the bus. The Hot Springs School District provides no reimbursement for this travel. The Oelrichs School District, on the other hand, provides reimbursement for any mileage beyond two and one half miles from the school. The circuit court found that if there was any advantage, it was •with Oelrichs, in light of the 44 miles of uncompensated travel per day required by the Hot Springs District.
[¶ 20.] Even though the Sides claim the Hot Springs District bus service is more convenient, takes less time and is on better roads, under the narrow standard of review, this Court finds there was sufficient evidence to show the evidentiary advantage was with the Oelrichs District.
[¶ 21.] 3. Whether the district line which places Sides’ property in the current district was drawn in an arbitrary fashion?
[¶ 22.] While the boundary of the Oelrichs School District does zigzag, there is no merit to the Sides’ contention that the property line which places them in the Oelrichs School District is arbitrarily drawn. It was rationally drawn to accommodate the choice of the residents of the former Smithwick School District at the time that District was dissolved. The line which places the Sides in the Oelrichs School District is not where the zigzag in the district occurs; the Sides’ property is one section north and straight across *913due east from the existing boundary. The Sides’ petition, on the other hand, would move that line eight and a half sections south and due east, creating a 32,380 acre “peninsula.” It is also ironic that the boundary that the Sides now claim is “arbitrary” was created at their own request when the Smi-thwick District dissolved.7 There was substantial evidence for the circuit court to find that the original boundary was not drawn in an arbitrary fashion and to find that the new boundary would be arbitrary.
[¶ 23.] 4. Whether petitioners’ children have special needs best met in the district petitioners are attempting to join?
[¶24.] The Sides claim that their children, particularly their oldest daughter, have special needs which are better met by the Hot Springs School District. While the evidence suggests that Amanda is academically and athletically gifted, the Sides have provided no supporting authority for their contention that she has special needs, and the issue is deemed waived. State v. Knoche, 515 N.W.2d 834, 840 (S.D.1994); Corbly v. Matheson, 335 N.W.2d 347, 348 (S.D.1983).8
[¶ 25.] 5. Whether the petitioners live closer to the school district they are joining as opposed to the district they are leaving?
[¶26.] As previously discussed, the Sides are geographically closer to the Oelriehs School District than to the Hot Springs District.
[¶ 27.] We note that the circuit court, after hearing all the testimony and considering all the evidence, concluded that the primary basis for the Sides’ petition was their personal preference that the children attend school in the Hot Springs district. Personal preference is not a sufficient basis for granting a boundary change petition. See, Old-ham-Ramona, Colman-Egan, supra.
[¶28.] The Sides additionally argue that the Oelriehs School Board based its decision on erroneous information which estimated the proposed boundary change would cause the school district to annually lose $19,999.07 in real property taxes and federal payments in lieu of taxes. It was later established that the true impact was $11,000. We have previously determined that economic factors, in conjunction with other relevant factors, are a valid consideration by the school board in considering a petition. Oldham-Ramona, 502 N.W.2d at 582 (emphasis added). Clearly an $11,000 loss in revenue for a school district the size of Oelriehs is no small matter.
[¶ 29.] While the economic loss to the school district may have been an important motivation of the school board,9 it was not the only factor board members considered. The record shows substantial evidence supporting the other factors, and we hold that the circuit court properly determined that the school board decision disapproving the boundary change was not arbitrary, capricious or an abuse of discretion.
[¶ 30.] We affirm.
[¶ 31.] MILLER, C.J. and KONENKAMP, J., concur. [¶ 32.] SABERS and AMUNDSON, JJ., dissent.. SDCL 13-6-85, which addresses minor boundary changes on petition by voters, states as follows, in part:
A boundary change, affecting not more than two percent of the assessed valuation and not more than two percent of the tax-exempt acreage or other tax-exempt property to be determined at the discretion of the school district from which the area is to be taken, may be made upon an application for a boundary change to the school board of the school district from which the area is to be taken and to the school board of the school district to which the area is to be annexed, in the form of a petition signed by over fifty percent of the *910voters residing in the area to be transferred by the boundary change.
School district concedes that the Sides’ petitions involve 1.98 percent of the total assessed valuation of the Oelrichs School District.
. SDCL 13-6-84.1 provides that in order to request a boundary change, ‘‘[t]he boundary of the area proposed to be transferred shall be coterminous at some point with the common boundary of the two school districts. Land owned by the federal, state or local governments ... may be included in the request.”
. SDCL 13-6-85 provides that the hearing may be held by the Secretary "or his representative.”
. The hearing lasted over seven hours on two non-consecutive days and included new testimony from John Sides and Board President Orval Frahm.
. We take judicial notice that the open enrollment bill, HB 1075, enacted by the 1997 Legislature, may provide some relief to the Sides. However, the law, which amends existing sections of SDCL ch. 13-28 and adds SDCL 13-28-40^47, will not take effect until July 1, 1997 and does not become fully implemented for purposes of school enrollment until the 1998-99 school year. Thus, the Sides' appeal is not moot.
. In hearing the appeal de novo, the circuit court properly considered all evidence presented to it in determining whether the school board’s decision was lawful. See, e.g., Iversen v. Wall Bd. of *912Educ., 524 N.W.2d 624 (S.D.1994); Oldham-Ramona, supra; Maasjo v. McLaughlin Sch. Dist. No. 15-2, 489 N.W.2d 618 (S.D.1992); Reid v. Huron Bd. of Educ., 449 N.W.2d 240 (S.D.1989); Strain, supra; Schnabel v. Alcester Sch. Dist. No. 61-1, 295 N.W.2d 340 (S.D.1980); Busker v. Board of Educ., 295 N.W.2d 1 (S.D.1980).
. When John Sides attended the Smithwick school, it was part of the old Smithwick School District. At the time that district dissolved, parents within the Smithwick District were given their preference of the Oelriehs or Hot Springs Districts. John’s parents chose the Oelriehs District because the school John attended at Smi-thwick was part of that District. The exercise of the option by various parents within the Smi-thwick District resulted in a zigzagging border between the Oelriehs and Hot Springs Districts, even within the town of Smithwick itself.
. A review of the statutes is suggestive that the term “special needs” deals with students with disabilities rather than those who are academically or athleticaEy gifted. See SDCL 13-33A-1 and ch 13-37.
.School Board President Orval Frahm testified that the school board looked at the factors it must consider. ‘‘[W]e were all aware of them and we spent, like I say, I thought a long time talking about the reasons—well, I'll be honest with you—to deny the boundary change.” However, Frahm further testified that the school board would not have made a different decision if the amount of financial impact would have been established at $11,000.
