OPINION
¶ 1 In this opinion, we consider the standard courts should apply in determimng whether a non-custodial parent’s voluntary decision to leave his or her employment to become a full-time student constitutes a sufficient change in circumstances to warrant a downward modification of the parent’s child support obligation.
I.
¶2 The parties divorced in November 1995. The court ordered appellant Billy L. Little, Jr., an Air Force lieutenant, to pay $1,186 per month for the support of his two young children. In August 1996, appellant resigned his commission in the Air Force, a position that paid $48,000 in yearly salary plus benefits, and chose to enroll as a full-time student at Arizona State University College of Law rather than to seek employment.
¶ 3 Upon leaving the Air Force, appellant petitioned the court to reduce his child support obligation to $239 per month. The trial court concluded that appellant had failed to prove a substantial and continuing change of circumstances in accordance with Arizona Revised Statutes (A.R.S.) §§ 25-327.A and 25-503.F, and denied Ms request for modification. The trial court specifically found that appellant voluntarily left his employment to further his own ambition; that he failed to consider the needs of Ms children when he made that decision; and that to reduce his child support obligation would be to his children’s immediate detriment and their previously established needs. The trial court did reduce appellant’s child support obligation to $972 per month on the ground that appellee Lisa L. Little had acquired a higher paying job. 1
¶ 4 The court of appeals, applying a good faith test to determine whether appellant acted reasonably in voluntarily leaving his employment, held that the trial court abused its discretion in finding that appellant’s decision to terminate his employment and pursue a law degree was unreasonable. Because we hold that a court, rather than rely upon a good faith test, must balance a number of factors to determine whether to modify a child support order to reflect a substantial and continuing change of circumstances, we vacate the opinion of the court of appeals and affirm the decision of the trial court.

¶ 5 The decision to modify an award of child support rests within the sound discretion of the trial.court and, absent an abuse of that discretion, will not be disturbed on appeal.

¶ 6 Arizona’s law governing modification of child support orders, codified at
*521
A.R.S. §§ 25-327.A and 25-503.F, states that a court should modify a child support order only if a parent shows a substantial, continuing change of circumstances. Guidelines adopted by this court provide procedural guidance in applying the substantive law.

¶ 7 Arizona’s appellate courts have considered whether a court should modify a child support order to reflect a change in an obligor parent’s employment in the contexts of incarceration, sale of a business, retirement, layoff, and strike. 2 We have not, however, considered the issue of what effect a parent’s voluntary decision to forego employment and become a full-time student has upon that parent’s obligation to pay child support.
¶ 8 A number of other jurisdictions have considered the issue that confronts us. Courts in sister jurisdictions have applied one of three tests to determine whether to modify a child support order when a parent voluntarily terminates his or her employment. See Lewis Becker, Spousal and Child Support and the “Voluntary Reduction of Income” Doctrine, 29 Conn. L. Rev. 647, 658 (1997). The first of these tests, the good faith test, “considers the actual earnings of a party rather than his earning capacity, so long as” he or she acted in good faith and not “primarily for the purpose of avoiding a support obligation” when he or she terminated employment. Id. The second test, designated the strict rule test, “disregards any income reduction produced by voluntary conduct and ... looks at the earning capacity of a party in fashioning a support obligation.” Id. The third test, referred to as the intermediate test, balances various factors to de- • termine “whether to use actual income or earning capacity in making a support determination.” Id. Each of the tests evidences its own strengths and weaknesses, and each reflects the public policy of its adopting jurisdiction.
¶ 9 Other jurisdictions have detected three fundamental flaws in the good faith test, which assigns the highest value to the obligor parent’s individual freedom of choice. First, the test erroneously “assumes that a divorced or separated party to a support proceeding will continue to make decisions in the best overall interest
of
the family unit,” when often, in fact, the party will not.
Id.
at 663. Second, the test fails to attach sufficient importance to a parent’s existing obligation to support his or her children.
See id.
at 664. As one court explained, the good faith test allows a parent to be “free to retire, take a vow of poverty, write poetry, or hawk roses in an airport, if he or she sees fit,” provided only that his or her motivation for acting is not to shirk a child support obligation.
Deegan v. Deegan,
¶ 10 The strict rule test also contains a fatal flaw. This test is too inflexible because it considers only one factor, the parent’s earning capacity, in determining whether to modify a child support order when a parent voluntarily leaves employment. See Becker, supra, at 668. We decline to adopt the strict rule test because it allows no consideration of the parent’s individual freedom' or of the economic benefits that can result to both parent and children from additional training or education.
¶ 11 We reject both these extreme approaches and instead adopt an intermediate balancing test that considers a number of factors, consistent with A.R.S. §§ 25-327.A, 25-503.F, 25-501.C, and the Guidelines.
D.
¶ 12 Arizona law prescribes that “[t]he obligation to pay child support is primary and other financial obligations are secondary.” A.R.S. § 25-501.C. Thus, the paramount factor a trial court must consider in determining whether a voluntary change in employment constitutes a substantial and continuing change in circumstances sufficient to justify a child support modification is the financial impact of the parent’s decision on the child or children the support order protects. If a reduction in child support due to a non-eustodial parent’s voluntary decision to change his or her employment status places a child in financial peril, then the court generally should not permit a downward modification.
¶ 13 In many instances, the impact on the children will not be so severe as to place the children in peril. In those circumstances, courts must consider the overall reasonableness of a parent’s voluntary decision to terminate employment and return to school. The answers to several questions will provide relevant information. The court should ask whether the parent’s current educational level and physical capacity provide him or her with the ability to find suitable work in the marketplace. If so, the decision to leave employment is less reasonable.
See Patterson v. Patterson,
¶ 14 We do not intend to suggest that the factors listed above are exhaustive of the relevant areas of inquiry. The primary task for a trial court is to decide each case based upon “ ‘the best interests of the child, ■ not the convenience or personal preference of a parent.’ ”
Department of Soc. Servs. v. Ewing,
¶ 15 We believe the balancing test described above comports not only with Arizona’s public policy, but also with a national policy trend that favors strictly enforcing child support obligations. Several states, including Alabama, Florida, Maine, Montana, New Mexico, Ohio, and Virginia, recently have held that a parent’s voluntary return to school does not justify a downward modification of his or her child support obligation.
See Overbey,
¶ 16 The court of appeals, rather than look to this development in public policy, instead relied upon a forty-year-old decision,
Nelson v. Nelson,
¶ 17 We reject the reasoning of Nelson for several reasons. First, its holding elevates a parent’s wishes and financial status above the best interests of his children. Second, the decision clearly contradicts our state legislature’s statutory mandate that “[t]he obligation to pay child support is primary and all other financial obligations are secondary.” A.R.S. § 25-501.C. Moreover, we disagree *524 with the notion that attending school full-time and fulfilling one’s child support obligation are mutually exclusive options, given that a divorced or separated parent can fill income gaps by participating in student financial aid programs and/or obtaining part-time employment. The court of appeals erred when it relied on Nelson.
¶ 18 Applying the balancing test to the facts involved here, we conclude that the trial court did not abuse its discretion when it refused appellant’s request for a downward modification of his child support obligation. First, the negative impact of the requested reduction on appellant’s children, had the trial court granted it, would have been substantial. The trial court found that such a reduction “would be to the children’s immediate detriment and their previously established needs.” The record alsocreveals that appellee earns only $1,040 per month in salary. This income places the Little family well below the 1998 federal poverty level. 3 Without their father’s support, appellant’s children would face significant economic hardship. Second, appellant holds Bachelor of Arts and Master of Business Administration degrees. Appellant, by asking the trial court to assume he will earn more money when he completes law school than he could have earned in the private business sector, invited the court to engage in speculation. Therefore, while appellant’s children are young enough to benefit from any increased income their father earns, the speculative nature of the increase justified giving this factor minimal weight. Third, the record does not reflect that appellant, upon leaving the Air Force, even attempted to obtain suitable employment in the Phoenix metropolitan area that would have allowed him to be close to his children and fulfill his financial obligations to them. Fourth, appellant has been able to finance his law school education and most of his child support obligation through student loans. Nothing in the record suggests that appellant is unable to obtain part-time employment to fulfill the remainder of his child support obligation. Finally, the trial court specifically found that appellant failed to act in good faith and instead endeavored to further his own ambition when he chose to forego employment and become a full-time student. Thus, the trial court did not abuse its discretion when it determined that appellant failed to act in his children’s best interests when he voluntarily left full-time employment to enroll in law school.

¶ 19 We realize that the “responsibilities of begetting a family many times raise havoc with dreams. Nevertheless, the duty [to support one’s children] persists, with full.authority in the State to enforce it.”
