PETERSON, J.

Here, an injured worker has been found capable of part-time work in an occupation, but her earnings would be approximately one-third of her pre-injury wages. She claims that her earnings are so greatly reduced as to entitle her to a permanent total disability (PTD) award. ORS 656.206 (1)(a) provides:

"`Permanent total disability' means the loss, including preexisting disability, of use or function of any scheduled or unscheduled portion of the body which permanently incapacitates the worker from regularly performing work at a gainful and suitable occupation. As used in this section, a suitable occupation is one which the worker has the ability and the training or experience to perform, or an occupation which the worker is able to perform after rehabilitation."

Claimant contends that the occupation that she has been found capable of performing part-time does not constitute a "gainful" occupation. She asserts:

"The maximum earnings claimant could make post-injury without training is less than one-third of what she earned pre-injury. * * * [T]his disparity between pre-injury and post-injury salary establishes that the jobs which the Board found claimant could perform, as a matter of law, do not constitute gainful employment."

Claimant, while working as a meat wrapper, suffered a back injury. Thereafter, claimant's back condition worsened, and she underwent a lumbar laminectomy and disectomy, left L4-5 and L5-S1 with an L4 through sacrum fusion. Claimant achieved a good result and returned to work in April 1981 without significant problems. In October 1984, while working for Albertson's, Inc. (employer), a self-insured employer, claimant slipped and almost fell, causing low back and bilateral leg symptoms. Claimant was off work for a brief period of time and then returned to work for three months, but was unable to continue. Claimant has not worked since mid-March 1985.

Before her October 1984 injury, claimant worked a 40-hour week at an hourly rate of pay of $10.90. Her gross weekly pay was $436. The record contains evidence that telemarketing and hotel/motel inspector jobs pay $4.75 and $4.00 per hour, respectively, and that claimant could earn from $80 to $142.50 per week for such part-time work. As a part-time hotel/motel inspector or telemarketer, claimant's earnings would be as little as 18.3 percent of her pre-injury weekly wage (20 hours work at $4 per hour), but no more than 32.7 percent of her pre-injury weekly wage (30 hours at $4.75 per hour).

The referee concluded that claimant was not capable of regularly performing work at a gainful and suitable occupation and thus was entitled to PTD benefits. The Workers' Compensation Board (Board) reversed that part of the referee's order, concluding that claimant was "employable without training as a telemarketer and hotel/motel inspector" and that such work was available. Claimant does not contest that finding. The Board concluded that claimant was entitled to an award of 75 percent unscheduled permanent partial disability. The Court of Appeals, with one judge dissenting, affirmed. Tee v. Albertsons, Inc., 107 Or. App. 638, 813 P.2d 574 (1991). We modify the decision of the Court of Appeals and remand the case to the Board.

ORS 656.206 (1) defines PTD as a loss "which permanently incapacitates the worker from regularly performing work at a gainful and suitable occupation." (Emphasis added.) The word "occupation" is modified by both "gainful" and "suitable." The term "suitable occupation" is defined in ORS 656.206 (1)(a) as "one which the worker has the ability and the training or experience to perform, or an occupation which the worker is able to perform after rehabilitation." The term "gainful occupation" is not defined by statute or rule. The decision in this case turns on the meaning of the term "gainful occupation" contained in the definition of PTD in ORS 656.206 (1)(a) of the Workers' Compensation Law.

Before 1987, workers' compensation appeals to the Court of Appeals were de novo. ORS 656.298 (6) (1985). In 1987, the legislature amended ORS 656.298 (6) to provide: "Review shall be as provided in ORS 183.482 (7) and (8)." Or Laws 1987, ch 884, § 12a. Appeals to the Court of Appeals and this court are no longer de novo; reviews are under the Administrative Procedures Act, ORS 183.482.

In ascertaining the meaning of "gainful occupation," we follow the methodology summarized in Springfield Education Assn. v. School Dist., 290 Or. 217, 223-30, 621 P.2d 547 (1980). In Springfield, this court discussed the allocation between administrative agencies and courts of responsibility for giving specific meaning to statutory terms. Id. at 221-30. The opinion divided statutory terms into three classes, each of which conveys to the agency different responsibilities for definition. The first class, terms of precise meaning, requires the agency only to apply the terms to the facts. The second class, inexact terms, comprises a complete expression of legislative policy and requires the agency to interpret the legislature's meaning, either by rule or by a decision in a contested case. The third class, terms of delegation, is incomplete legislation that the agency is authorized to complete, by making rules within the range of discretion established by the statutes. Id. at 223.

The term "gainful occupation" in ORS 656.206 (1)(a) is a statutory term within the second class described in Springfield. That is, it is a statutory term that embodies a complete expression of legislative meaning, even though its exact meaning is not necessarily obvious. To determine the intended meaning of an inexact statutory term, this court "look[s] to extrinsic indicators such as the context of the statutory term, legislative history, a cornucopia of rules of construction, and [its] own intuitive sense of the meaning which legislators probably intended to communicate by use of the particular word or phrase." Id. at 224. The ultimate inquiry is what the legislature intended by using the term. Ibid. The determination of the meaning of a statutory term is one of law, ultimately for the court. Ibid. Thus, the inquiry in this case is: What did the legislature intend by using the word "gainful" in ORS 656.206 (1)(a)?

Claimant makes several arguments in support of her contention that a "gainful" occupation, ORS 656.206 (1)(a), is one that pays a wage comparable to the worker's pre-injury wage. First, she contends that the court, in interpreting the word "gainful," as used in ORS 656.206 (1)(a), should adopt the statutory definition of "suitable employment" found in ORS 656.340 (6)(b)(B)(iii), a definition that is used to determine whether an injured worker is entitled to vocational assistance, and that incorporates comparability of pre-injury and post-injury wages. Under ORS 656.340, an injured worker who is not able to obtain "suitable employment" may be entitled to vocational assistance, at the expense of the insurer or self-insured employer, to enable the worker to achieve "a wage as close as possible to the worker's wage at the time of injury." ORS 656.340 (5). "Suitable employment" is defined, in part, as "[e]mployment that produces a wage within 20 percent of that currently being paid for employment which was the worker's regular employment." ORS 656.340 (6)(b)(B)(iii). Claimant argues that that definition of what constitutes "suitable" employment should apply in the determination of PTD.

The major flaw in claimant's argument is that the definition of "suitable employment" on which she relies is limited to the statute containing the definition. ORS 656.340 (6)(b)(B) provides: "As used in this subsection[,] * * * `[s]uitable employment' means * * *." That definition is not applicable to the determination of eligibility for PTD benefits. The PTD statute, ORS 656.206 (1)(a), contains its own definition of "suitable occupation." As already noted, that definition provides that, "[a]s used in this section, a suitable occupation is one which the worker has the ability and the training or experience to perform, or an occupation which the worker is able to perform after rehabilitation." ORS 656.206 (1)(a). Comparability to pre-injury wages is not part of that definition. Claimant wants "suitable" to mean "suitable" and "gainful" to mean "suitable." By using the word "gainful" in ORS 656.206 (1)(a), the legislature signaled its intention that "gainful occupation" means something different from "suitable occupation," the difference being that a "gainful occupation" is an occupation for profitable remuneration. There is nothing to suggest that the definition of "suitable employment" in ORS 656.340 (6)(b)(B) applies to a determination of PTD or in any context other than a determination under subsection (6) of ORS 656.340. ORS 656.340 (6)(b)(B) provides no basis for adopting the definition proposed by claimant.

Claimant next argues that the court should interpret the term "gainful" (which is not defined in ORS 656.206 or elsewhere) as the equivalent of "suitable" as defined in ORS 656.340 (6)(b)(B)(iii). Claimant contends that not requiring comparability of wages for purposes of ORS 656.206 (1)(a) is contrary to the purposes for which the Workers' Compensation Law was enacted. Claimant asserts that denying her PTD benefits because she is capable of regular part-time, low-paying employment is not consistent with the objective of returning "the injured worker physically and economically to a self-sufficient status in an expeditious manner and to the greatest extent practicable." ORS 656.012 (2)(c).

There are two flaws in that argument. One is that it gives no weight to the significant difference between the specific goal of vocational assistance — which is to "return the worker to employment which is as close as possible to the worker's regular employment at a wage as close as possible to the worker's wage at the time of injury," ORS 656.340 (5) — and the broader goal of the Workers' Compensation Law — which is "[t]o restore the injured worker physically and economically to a self-sufficient status," ORS 656.012 (2)(c). Second, claimant's argument discounts the different roles played by the PTD benefits statute and the vocational assistance statute and virtually ignores the existence and role of the statute providing for permanent partial disability (PPD) benefits, ORS 656.214, in achieving the declared objectives of the Workers' Compensation Law.

An award of PTD or PPD benefits aims to compensate an injured worker for permanently lost earning capacity, thereby promoting the goal of returning the worker to economic self-sufficiency. An injured worker who is incapable of regularly working at a gainful and suitable occupation is entitled to PTD benefits. ORS 656.206 (1)(a). An injured worker who is not permanently totally disabled, but suffers from an unscheduled PPD, is entitled to compensation for that proportion of earning capacity permanently lost as a result of a compensable injury. ORS 656.214 (5). PPD benefits aim to compensate the worker who is capable of regular work, but whose earning capacity has been diminished permanently as a result of injury.

Vocational assistance, on the other hand, aims to ameliorate lost earning capacity by retraining. It promotes the general goal of self-sufficiency by assisting permanently disabled workers to achieve wages comparable to their pre-injury wages. ORS 656.340 (6) and (14). If vocational assistance is successful, the injured worker's status may be re-evaluated to allow for a reduction in the extent or for the complete elimination of permanent disability benefits. See ORS 656.206 (5) (requiring insurers to re-examine PTD claims every two years); ORS 656.325 (3) (awards of PTD and unscheduled PPD benefits shall be subject to periodic examination and adjustment). Because vocational assistance serves a different purpose than that served by PTD and PPD benefits, there is no sound reason for interpreting the term "gainful" in ORS 656.206 (1)(a) as equivalent to "suitable" as defined in ORS 656.340 (6)(b)(B)(iii).

Claimant relies on Harris v. SAIF, 292 Or. 683, 642 P.2d 1147 (1982), which also concerned eligibility for PTD benefits. There, the court determined that an injured worker who earned substantial income on real estate investments still could be entitled to PTD benefits, because the criterion for PTD is not income, but employability. 292 Or at 694-95. The court stated the test as follows:

"The determination of [PTD] status does not turn upon whether the claimant has money-earning capacity, but rather upon whether the claimant is currently employable or able to sell his services on a regular basis in a hypothetically normal labor market." Id. at 695.

The claimant's active, albeit irregular, participation in his real estate investment activities, and his ability thereby to earn income did not mean that he was no longer permanently totally disabled. Id. at 695-96. The Harris court remanded the case to the Board for a determination of the claimant's employability at some occupation. Id. at 697. Harris does not apply here, because the question that claimant raises is not whether claimant is employable (which was the issue in Harris), but rather whether the occupation that she is deemed capable of performing is gainful.

Requiring post-injury employment to produce a wage comparable to a worker's pre-injury wage, in order to be "gainful," would judicially overrule, at least in part, the statutory provision for unscheduled PPD. According to claimant's argument, any worker with a permanent disability who is not capable of post-injury employment that would produce 80 percent of the wages paid for the worker's pre-injury employment would be entitled to PTD benefits. PPD benefits thus would be limited to workers whose earning capacity was diminished less than 20 percent as a result of an unscheduled permanent disability. There is nothing in the PPD statute that indicates that it is so limited. The legislature has created a system that compensates unscheduled PPD on the basis of its permanent effect on earning capacity. The decision to compensate injured workers for unscheduled PPD reflects a policy choice that such workers should be required to earn that portion of their income that they are capable of earning in regular employment. PPD benefits are for injured workers who are permanently partially disabled.

Having rejected claimant's contentions concerning the meaning of "gainful occupation," our "ultimate task [is] to discern and apply the legislature's intended meaning." Springfield Education Assn. v. School Dist., supra, 290 Or at 217. As stated, ORS 656.206 (1)(a) itself defines a "suitable occupation" as "one which the worker has the ability and the training or experience to perform, or an occupation which the worker is able to perform after rehabilitation." The definition of "suitable occupation" concerns work that the worker is capable of performing, irrespective of the remuneration received for the work. What is the worker capable of doing? By contrast, the term "gainful occupation" concerns remuneration; it relates to the earnings that the worker can obtain by working at a "suitable occupation." The plain and ordinary meaning of "gainful" is "profitable, lucrative: gainful employment." The Random House Dictionary of the English Language 782 (2d ed 1987) (emphasis in original). The term "gainful occupation" contained in the definition of PTD in ORS 656.206 (1)(a) means profitable remuneration.

The Board found that "both the telemarketing job and the hotel/motel room inspectress jobs were gainful and suitable employments for claimant." It then "concluded that claimant is not permanently and totally disabled" and awarded claimant an unscheduled permanent disability of 75 percent. The Board did not have the benefit of this opinion in deciding whether claimant's part-time employment was for profitable remuneration. Its decision was not made in light of the meaning of "gainful occupation" contained in this opinion. Because this is the first decision of this court interpreting the meaning of "gainful occupation," and because the Board is the appropriate body to apply the meaning of "gainful occupation" under the facts of this case in performing its factfinding function, it is appropriate to remand this case to the Board for further consideration in light of this opinion.

Therefore, the decision of the Court of Appeals is modified, and this case is remanded to the Workers' Compensation Board for further consideration.
