Opinion by
Judge Smith,Claimant, Lynn Greenawalt, appeals from a March 2, 1987 decision of the Unemployment Compensation Board of Review (Board) which affirmed the referees determination that Claimant was ineligible for benefits under Section 401 as defined in 4(u) and Section 401(c) of the Pennsylvania Unemployment Compensation Law (Law).1 The Board determined that Claimant received a fault overpayment of $828.00 subject to recoupment under Section 804(a) of the Law.2 We reverse in part the Boards decision.
Claimant filed an application for benefits with an effective date of June 9, 1985. The Office of Employment Security (OES) initially determined Claimant to be eligible for benefits but after receiving reports of Claimants part-time earnings, the OES issued a determination that Claimant was ineligible for benefits for certain compensable weeks and imposed a fault overpayment.
*98On appeal by Claimant, the referee affirmed the OES determination. The Board affirmed the referee, and upon reconsideration of its decision, issued a decision and order on March 2, 1987 again affirming the referee.
Claimant was employed part-time in November 1985 by Home Health Help, Inc.3 Claimants reported wages as a private duty nurse for weeks ending June 15, 1985 through December 28, 1985 were $56.00 per week, except for the week ending December 28 which were $27.52. The Board found that Claimant earned additional income during the weeks ending November 9, 1985 through December 28, 1985 and that she was absent from work the week ending December 7, 1985 and could have earned an additional $91.00 in wages as employment was available to her. Home Health Help, Inc. completed Claimants earnings reports which Claimant was required to deliver to OES. The Board found that Claimants correct earnings for the weeks ending November 9, 1985 through December 28, 1985 were greater than the reported earnings and, as a consequence, Claimant received an $828.00 overpayment of benefits through her own fault.
This Courts scope of review in unemployment compensation cases is to determine whether any constitutional rights have been violated; an error of law was committed; or findings of fact were not supported by substantial evidence of record. Estate of McGovern v. State Employees Retirement Board, 512 Pa. 377, 517 A.2d 523 (1986); Kirkwood v. Unemployment Compensation Board of Review, 106 Pa. Commonwealth Ct. 92, 525 A.2d 841 (1987). Substantial evidence has been defined as relevant evidence upon which a reasonable *99mind could base a conclusion. Johnson v. Unemployment Compensation Board of Review, 94 Pa. Commonwealth Ct. 24, 502 A.2d 738 (1986).
Claimant argues that the Boards fault overpayment decision is not supported by substantial evidence of record. The Board found that Claimants corrected earnings should have been reported to OES and that Claimant failed to present a reasonable explanation for the discrepancy in earnings. With respect to available work during the week ending December 7, 1985, the Board noted that Claimant failed to present a written contract to substantiate any agreement with her employer to work every other weekend and that she had in feet worked every weekend prior to the week ending December 7, 1985. Based upon this reasoning, the Board concluded that Claimant received the overpayment of benefits through her own fault.
The record is devoid of any findings which prove Claimants fault in the reporting of income. To find a discrepancy between the originally reported earnings and the corrected earnings without more is insufficient to support the Boards conclusion of fault. To find fault, the Board must make some findings with regard to Claimants state of mind. Maiorana v. Commonwealth of Pennsylvania, Unemployment Compensation Board of Review, 70 Pa. Commonwealth Ct. 614, 453 A.2d 747 (1982). “ ‘Fault,’ within the meaning of Section 804(a), has been defined as ‘an act to which blame, censure, impropriety, shortcoming or culpability attaches. Cruz v. Unemployment Compensation Board of Review, 110 Pa. Commonwealth Ct. 117, 120, 531 A.2d 1178, 1180 (1987). Conduct designed improperly and intentionally to mislead OES is sufficient to establish a fault overpayment. Summers v. Unemployment Compensation Board of Review, 60 Pa. Commonwealth Ct. 146, 430 A.2d 1046 (1981).
*100Claimant testified that her employer prepared the wage report records which were submitted to OES by Claimant; and that upon receiving notice of an overpayment, she contacted OES and discovered that the records’prepared by her employer had been destroyed. OES presented no witnesses at the hearing. Claimant does not dispute that ah overpayment of benefits did occur,- but challenges the Boards decision that the overpayment was due to Claimants fault. The record thus lacks substantial evidence to support the Boards finding that Claimant received an overpayment of benefits through her own fault.
Finally, Claimant argues that the evidence does not support the Boards finding that she was absent from available work the week ending December 7, 1985 and that she could have earned an additional $91.00 in wages. Considering the record as a whole, substantial evidence does exist of support this finding of the Board. Since Claimant worked every weekend during the period -in question, it was reasonable to assume that work was available during the weekend of December 7. Claimants argument in this regard is therefore rejected.
Accordingly, the Boards decision as to the denial of benefits, is affirmed, and reversed as to the finding of fault by Claimant. This: Court, finds the $828.00 overpayment to be a non-fault overpayment subject to recoupment under provisions of Section 804(b)4 of the Law which govern recoupment of non-fault overpayments.
