WARREN, J.
Plaintiffs are three female school teachers who were employed by defendant school district. They commenced this action for damages under the state and federal equal pay acts, ORS 652.220 and 29 USC § 206 (1982), claiming that defendant paid them less than it paid male employes for comparable and equal work during the period September, 1980, to September, 1982.
After a trial to the court, the trial court entered a judgment for defendant. Plaintiffs appeal and argue that the trial court applied improper rules concerning the parties’ burdens of proof and, therefore, failed to analyze the evidence properly.
Plaintiffs Swails and Rohweder were full-time teachers of regular classes during both academic years at issue. Plaintiff Smith was the Title I-Resource Room teacher, who worked with children with special educational needs. Smith was employed only during the 1980-81 school year and on a four-fifths time basis. All three plaintiffs had similar responsibilities for supervising students and planning classes, and all were required to have a valid Oregon teaching certificate. They all signed the same type of contract and had the same job description.
ORS 652.220 provides, in pertinent part:
“(1) No employer shall:
“(a) In any manner discriminate between the sexes in the payment of wages for work of comparable character, the performance of which requires comparable skills.
“(b) Pay wages to any employe at a rate less than that at which the employer pays wages to employes of the opposite sex for work of comparable character, the performance of which requires comparable skills.
“(2) Subsection (1) of this section does not apply where:
“(a) Payment is made pursuant to a seniority or merit system which does not discriminate on the basis of sex.
“(b) A differential in wages between employes is based in good faith on factors other than sex.”
The effects of the state and federal
equal pay acts are substantially the same. Both prohibit the payment of different wages to members of the opposite sexes for the performance of comparable or equal work, unless the differential is based on one of several enumerated nondiscriminatory factors. One difference between them is that the federal act refers to “equal” work, whereas the state act refers to “comparable” work, which is a more inclusive term. There is no dispute that all plaintiffs were performing work equal to the male teachers. The issue is whether the trial court properly perceived and allocated the parties’ burdens of proof with regard to discrimination in compensation and whether its finding that there was not discrimination is supported by substantial evidence. Because the two acts are so similar, we shall discuss only the state act, but our holding applies equally to the federal claim.
It is not difficult for a plaintiff to make a
prima facie
case under ORS 652.220(1) (b). Plaintiffs simply had to show that they were performing work comparable to that of male teachers and that they were paid less than male teachers. In actions for unequal pay under 652.220(1)(b), plaintiffs do not have the burden of proving that the pay differential was based on sex. Rather, the burden is on the defendant to prove as an affirmative defense that the pay disparity is based on a particular factor other than sex as provided in ORS 652.220(2). Plaintiffs’ and defendant’s burdens under 29 USC § 206(d)(1) (1982) are the same.

prima facie
case of discrimination a plaintiff must prove “that the facts give rise to the permissible inference that the wage disparity was based
on sex.”

As stated above, plaintiffs proved that they performed work equal to male teachers. The only remaining issue is whether they were paid less than male teachers. Before the 1980-81 school year, defendant paid teachers according to a salary schedule which reflected their experience and education. The district abandoned the schedule for the two years in issue and subsequently reinstated it. The salaries of plaintiffs and the district’s male and some other female teachers for 1980-82 were:
Annual Salary
Teacher (Sex) 1980-81 1981-82
Swails (PI) (F) $16,500 $17,693
Rohweder(Pl) (F) 13,500 14,500
Smith (PI) (F) 13,750
Roberts (F) 13,000
Olsen (M) 17,500
Snider (F) 17,500
Haas (M) 17,500
Schmitz (M) 14,000
It is apparent from the table that, in 1980-81, the one male teacher was paid more than each of the female plaintiffs. In 1981-82, Swails was paid more than both male teachers, and Rohweder was paid less than one and more than the second male teacher. All plaintiffs proved that they were paid less than male teachers in 1980-81. Rohweder proved that she was paid less than a male teacher in 1981-82. Plaintiffs made a
prima facie
case.
Defendant alleged as affirmative defenses that the disparities were based on a merit system and in good faith on factors other than sex. In support, defendant offered evidence to prove two points. First, its witnesses testified that the district had received complaints about some of the plaintiffs, was not completely satisfied with their work and paid them less than other teachers to provide an incentive to improve their performance. Second, defendant’s witnesses testified that the district desired to improve the quality of its faculty and that it had to pay new teachers, male and female, higher
salaries to entice them to come to the school, which was in an isolated rural location.
Plaintiffs argue that the trial court labored under the mistaken impression that plaintiffs had to prove discrimination based on sex. For example, the court stated in its memorandum opinion:

Plaintiffs are three female school teachers who were employed by defendant school district. They commenced this action for damages under the state and federal equal pay acts, ORS 652.220 and 29 USC § 206 (1982), claiming that defendant paid them less than it paid male employes for comparable and equal work during the period September, 1980, to September, 1982.

They all signed the same type of contract and had the same job description.
ORS 652.220 provides, in pertinent part:
“(1) No employer shall:

“(b) Pay wages to any employe at a rate less than that at which the employer pays wages to employes of the opposite sex for work of comparable character, the performance of which requires comparable skills.
“(2) Subsection (1) of this section does not apply where:
“(a) Payment is made pursuant to a seniority or merit system which does not discriminate on the basis of sex.

The effects of the state and federal
equal pay acts are substantially the same. Both prohibit the payment of different wages to members of the opposite sexes for the performance of comparable or equal work, unless the differential is based on one of several enumerated nondiscriminatory factors. One difference between them is that the federal act refers to “equal” work, whereas the state act refers to “comparable” work, which is a more inclusive term. There is no dispute that all plaintiffs were performing work equal to the male teachers. The issue is whether the trial court properly perceived and allocated the parties’ burdens of proof with regard to discrimination in compensation and whether its finding that there was not discrimination is supported by substantial evidence. Because the two acts are so similar, we shall discuss only the state act, but our holding applies equally to the federal claim.
It is not difficult for a plaintiff to make a
prima facie
case under ORS 652.220(1) (b). Plaintiffs simply had to show that they were performing work comparable to that of male teachers and that they were paid less than male teachers. In actions for unequal pay under 652.220(1)(b), plaintiffs do not have the burden of proving that the pay differential was based on sex. Rather, the burden is on the defendant to prove as an affirmative defense that the pay disparity is based on a particular factor other than sex as provided in ORS 652.220(2). Plaintiffs’ and defendant’s burdens under 29 USC § 206(d)(1) (1982) are the same.

As stated above, plaintiffs proved that they performed work equal to male teachers. The only remaining issue is whether they were paid less than male teachers. Before the 1980-81 school year, defendant paid teachers according to a salary schedule which reflected their experience and education. The district abandoned the schedule for the two years in issue and subsequently reinstated it. The salaries of plaintiffs and the district’s male and some other female teachers for 1980-82 were:
Annual Salary
Teacher (Sex) 1980-81 1981-82
Swails (PI) (F) $16,500 $17,693
Rohweder(Pl) (F) 13,500 14,500
Smith (PI) (F) 13,750
Roberts (F) 13,000
Olsen (M) 17,500
Snider (F) 17,500
Haas (M) 17,500
Schmitz (M) 14,000
It is apparent from the table that, in 1980-81, the one male teacher was paid more than each of the female plaintiffs. In 1981-82, Swails was paid more than both male teachers, and Rohweder was paid less than one and more than the second male teacher. All plaintiffs proved that they were paid less than male teachers in 1980-81. Rohweder proved that she was paid less than a male teacher in 1981-82. Plaintiffs made a
prima facie
case.
Defendant alleged as affirmative defenses that the disparities were based on a merit system and in good faith on factors other than sex. In support, defendant offered evidence to prove two points. First, its witnesses testified that the district had received complaints about some of the plaintiffs, was not completely satisfied with their work and paid them less than other teachers to provide an incentive to improve their performance. Second, defendant’s witnesses testified that the district desired to improve the quality of its faculty and that it had to pay new teachers, male and female, higher
salaries to entice them to come to the school, which was in an isolated rural location.
Plaintiffs argue that the trial court labored under the mistaken impression that plaintiffs had to prove discrimination based on sex. For example, the court stated in its memorandum opinion:
“The evidence indicates that the main theme of the Board was to attempt to improve the quality of education provided at the elementary level, the reasons of the individual board members varied and the Court is in no way attempting to evaluate their reasoning but merely to
determine if it indicates a difference in pay based on sex discrimination.
* * * [T]he Board hired other teachers, male and female, at higher and lower salaries than the salaries paid the plaintiffs which in the Court’s opinion demonstrates a lack of ‘any salary system’ other than personal opinions of the Board’s members and their desire to improve the quality of teaching. The fact is that the ‘lack of system’ or schedule created morale problems, and Board criticism was a natural result of the lack of clear thinking on the part of the Board but
does not demonstrate hiring bias based on sex.
“Based on the evidence, the Court is of the opinion that the
plaintiffs have failed to prove the merits of their claims
and the Court finds in favor of the defendant.” (Emphasis supplied.)
The trial court also stated in its judgment its conclusion that “the evidence presented failed to support the allegations of plaintiffs’ claim.”
Plaintiffs argue that from these statements the trial court may have imposed on plaintiffs the burden to prove discrimination based on sex and concluded that they did not make a
prima facie
case. It is apparent, however, that the trial court considered all the evidence and concluded that defendant proved that the pay differential was based in good faith on factors other than sex. The trial judge’s statements are ambiguous. Because there were no special findings, we cannot tell whether the trial court allocated and applied the correct . burdens of proof in reaching its decisions. In the absence of special findings, we assume that the trial court applied the correct standard and review the decision to determine if the judgment is supported by substantial evidence.
Defendant offered evidence that it paid some new teachers more than plaintiffs because it believed, in good faith, that the new teachers were more qualified. A claim that certain employes were paid more than others because they are better qualified and not because of their sex, if made in good faith and believed by the trier of fact, is a defense under ORS 652.220(2).
The defense here is bolstered by the fact that one new female teacher (Snider) was paid equally to two new male teachers and more than one new male teacher. There is credible evidence which would support the conclusion that defendant proved its affirmative defense.
Affirmed.
