SAIF seeks review of a Department of Insurance and Finance (DIF) order holding that SAIF should not have assessed King Construction, Inc. (King) workers’ compensation insurance premiums for two workers.
King is a residential drywall contractor insured by SAIF. As a drywall contractor, King supplied all the necessaiy materials to Crawford and Morgan, who provided their own tools, established their own schedule, and were paid on the basis of square footage for the work that they did. SAIF assessed premiums for amounts King paid to Crawford and Morgan between July 1, 1989 and June 30, 1990, because it said they were employees. King appealed to DIF. DIF determined that Crawford and Morgan were sole proprietors from July 1, 1989 through October 2, 1989. It also determined that they were either sole proprietors or independent contractors from October 3, 1989 through June 30, 1990. Their status as independent contractors was on the basis of ORS 670.600, which became effective October 3,1989. DIF then ordered SAIF to rebill King, deleting premiums charged for Crawford and Morgan. SAIF seeks review of that order, assigning error to DIF’s determination that Crawford and Morgan were either sole proprietors or independent contractors for the policy period.
As to the period July 1, 1989 through October 2, 1989, DIF’s conclusion that Crawford and Morgan were exempt from ORS chapter 656 because they were sole proprietors is error. Little Donkey Enterprises, Inc. v. SAIF, 118 Or App 54, 845 P2d 1298 (1993). Because DIF made no findings concerning Crawford and Morgan’s status as independent contractors during that period, we must remand for that determination.
As to the period October 3, 1989 through June 30, 1990, there is substantial evidence to support DIF’s order that Crawford and Morgan were independent contractors under the criteria of ORS 670.600,1 including evidence that *423King’s only requirement was that Crawford and Morgan’s work meet industry performance standards. Contrary to SAIF’s argument, the fact that there is only one method to achieve an acceptable standard of performance does not mean that an individual is not “free from direction and control over *424the means and manner of providing the labor or services” under ORS 670.600(1).
Reversed and remanded for reconsideration.
ORS 670.600 provides:
“As used in various provisions of ORS chapters 316, 656, 657 and 701, an individual or business entity that performs labor or services for remuneration shall be considered to perform the labor or services as an ‘independent contractor’ if the standards of this section are met:
