United Cerebral Palsy (Employer) petitions for review of the March 12, 1993 order of the Workers’ Compensation Appeal Board, in which the Board modified Claimant Judith Emph’s benefits based on the wage rate of the first job referral which Claimant failed to pursue in good faith, thereby reversing the Referee’s suspension of Claimant’s benefits based on the wage rate for a later-referred job which exceeded Claimant’s pre-injury wages.
The sole issue raised by Employer is whether, under The Pennsylvania Workers’ Compensation Act,1 where a claimant receives numerous job referrals which he or she fails to pursue in good faith, the employer is only entitled to a modification of benefits based on the wage rate of the first-referred job or is also entitled to a modification or suspension of benefits based on the wage rate of a subsequently-referred job paying higher wages.2
We conclude that the Board improperly determined that the Referee had erred in suspending Claimant’s benefits based on the wage rate of the later-referred job. However, we also conclude that the Referee improperly based his decision on the dates of the job referrals without determining whether the jobs were available on those dates. Therefore, we vacate and remand.
Background
The relevant history of this case, as found by the Referee, is summarized as follows. Claimant while working as a resident program trainee for Employer sustained a work-related low back injury on May 13, 1988 for which she began receiving compensation in the amount of $160.07 pursuant to a Notice of Compensation Payable. Following a physical examination on July 6, 1989, Employer’s physician released Claimant to return to work.
Beginning on August 19, 1989, Employer sent Claimant referrals to ten suitable jobs within Claimant’s physical limitations. Claimant failed to follow up on eight of Employer’s referrals. The first referral to which Claimant failed to respond was for a *171telephone sales position at Sears & Roebuck, for twenty to twenty-five hours per week at $5.00 per hour. The second referral was for a clerk/cashier position at Dairy Mart, for twenty-four to forty hours per week at $8.70 per hour. The third was for a hostess position at Valleybrook Country Club, for forty to forty-eight hours per week at $5.00 to $6.00 per hour. Employer then filed a suspension/modification petition, alleging that, as of August 19, 1989, Claimant had sufficiently recovered from her work-related injury to return to gainful employment and that Claimant had failed in good faith to pursue numerous jobs available to her as of that time.
During the course of the hearings before the Referee, Claimant stipulated that she had returned to light-duty work with another employer from September 11, 1990 through March 31, 1991 at wages equal to or greater than her pre-injury wages.
In his December 5, 1991 order, the Referee suspended Claimant’s benefits as of August 19, 1989 for her failure to pursue Employer’s job referrals in good faith. The Referee based the suspension of Claimant’s benefits on the wage rate for the Valleybrook job, the third job referred, which, according to the Referee, offered earnings that exceeded Claimant’s pre-injury wages. The Referee also concluded that Employer was entitled to a suspension of benefits for the period of Claimant’s light-duty employment from September 11, 1990 through March 31, 1991.
The Board initially affirmed the Referee’s order. After a rehearing, however, the Board reversed the suspension of benefits for all but the period of Claimant’s light-duty employment. For the remaining time beginning August 19,1989, the Board ordered only a modification of Claimant’s benefits based on the wage rate of the Sears job. The Board held that the Referee had erroneously suspended Claimant’s benefits based on the wage rate of the Valleybrook job, reasoning that Associated Plumbing v. Workmen’s Compensation Appeal Board (Hartzog), 126 Pa.Commonwealth Ct. 618, 560 A.2d 865 (1989), requires the Referee to base a modification on the wage rate of the first suitable job which a claimant does not pursue in good faith.
On appeal to this Court, Employer argues that the Board erred in determining that an Employer is entitled to a modification of benefits based only the wage rate of the first job referral. Employer contends that the humanitarian principals of Associated Plumbing do not apply to this case because, unlike the Associated Plumbing claimant, who had responded to a majority of the employer’s job referrals, Claimant in this case failed to respond to eighty percent of Employer’s referrals. Therefore, according to Employer, the Referee properly suspended Claimant’s benefits based on the Valley-brook job.
Claimant was precluded from filing a brief before this Court.
Discussion
Under Kachinski v. Workmen’s Compensation Appeal Board (Vepco Construction Co.), 516 Pa. 240, 532 A.2d 374 (1987), an employer who seeks to modify a claimant’s benefits on the basis that the claimant has recovered some or all of his ability must first produce medical evidence of a change in condition. The employer must then produce evidence of a referral to an open job (or jobs), which fits within the occupational category for which the claimant has been given medical clearance. Id. The claimant must then demonstrate that he has in good faith followed through on the job referral(s). Id.
A claimant’s failure to pursue in good faith any suitable job referrals entitles the employer to a modification of benefits. Id. In our recent opinion of Castro v. Workmen’s Compensation Appeal Board (Albert Einstein Medical Center), — Pa.Commonwealth Ct. -, 645 A.2d 1377 (1994), we permitted a modification of the claimant’s benefits based on the wage rate of the first available job and permitted a suspension of the claimant’s benefits based on a later-available job. As we noted in Castro, our holding in Associated Plumbing requires that the modification of benefits be effective as of the date of the first available job which the claimant did not pursue in good faith. Again, *172as we stated in Castro, nothing in Associated Plumbing prevents a Referee from then suspending the claimant’s benefits based on a later-available job, offering wages equal to or greater than the claimant’s pre-injury wages.
The Board, therefore, misconstrued Associated Plumbing to limit Employer to a modification based on the first available job alone. The Referee was not precluded from suspending Claimant’s benefits based on the Valleybrook job.3 However, the Referee erred in suspending Claimant’s benefits as of the date of the Sears job referral. As noted above, the operative date in a modification of benefits is the date that a job was available to the claimant, which may post-date the date of the job referral. Further, a modification is effective as of the date of the first available job and is based on the wage rate of that job. A further modification or suspension of benefits based on the wage rate of a later-available job is not effective until the date that that job was available to the claimant.
Therefore, we vacate the Board’s order and remand for findings of fact and conclusions of law consistent with this opinion.
ORDER
AND NOW, this 12th day of October, 1994, the orders of the Workers’ Compensation Appeal Board dated March 12, 1993 at Nos. A92-0091 and A92-0092 are hereby vacated and these matters are remanded to the Workers’ Compensation Appeal Board for findings of fact and conclusions of law consistent with this opinion.

Our scope of review is limited to determining whether constitutional rights were violated, an error of law was committed, or whether necessary findings of fact are supported by substantial evidence. Bethenergy Mines, Inc. v. Workmen’s Compensation Appeal Board (Sebro), 132 Pa.Commonwealth Ct. 288, 572 A.2d 843 (1990).
. The record shows that the Valleybrook job was a full-time position at forty to forty-eight hours per week, offering wages between five and six dollars per hour, depending on the employee's experience. (R.R. at 163a.) Based on these figures, the Referee determined that the Valley-brook job would have generated an earning power between $160.00 and $240.00 per week. Because the $240.00 per week rate exceeded Claimant’s pre-injury wage rate of $177.85 per week, the Referee suspended Claimant's benefits. We find that the Referee appropriately used forty-eight hours in his calculation of Claimant's earning power because Claimant had been medically cleared to perform the Valleybrook job. Kurtiak v. Workmen’s Compensation Appeal Board (Western Sizzlin’ Steak House), 160 Pa.Commonwealth Ct. 637, 635 A.2d 732 (1993). We question the Referee’s apparent assumption that Claimant would have earned six rather than five dollars per hour at Valleybrook, but we note that even at $5.00 per hour, the Valleybrook wages would have exceeded Claimant's pre-injury wages.
