OPINION
¶ 1 This is an appeal from order of the Workers’ Compensation Court three-judge panel, affirming the trial court’s denial of benefits based on a finding that claimant’s injury did not arise out of and in the course of her employment. Based on our review of the record on appeal and applicable law, we reverse the order.
¶ 2 Claimant Barbara Barre filed her Form 3 on August 29, 1997, alleging she *876 injured her shoulders, arms and left hand when she slipped and fell while ascending the interior stairs to reach the second-floor office where she worked as a sales associate for Employer TCIM Services, Inc. Employer denied that Claimant suffered an injury arising out of and in the course of her employment.
¶ 3 At trial, Claimant was the only witness to testify. She testified that her accident occurred on August 12,1997, at approximately 7:30 a.m., as she arrived for work. It was raining that day.
¶4 Employer leased the entire building where Claimant worked. In addition to the stairs, there also was an elevator that could be used to reach Claimant’s second-floor work station. Claimant had used both the public stairs and the public elevator during her one-year period of employment; on this day, she chose the stairs.
¶ 5 On cross-examination, counsel for Employer questioned Claimant regarding her fall, and the following exchange occurred:
Q. To the best of your knowledge, was there anything on the stairs that you tripped on, like someone had left something there, or there was any fluid or anything?
A. I don’t know.
Q. As far as you know, you just slipped and fell?
A. I just — To my knowledge. I don’t know.
Q. And you were there; I mean I wasn’t. So when you fell, were your clothes wet because there was any type of puddle or anything?
A. It was raining that day. I wouldn’t know.
Q. Okay. But it wasn’t like there was an object that you know you stepped on and twisted your ankle and fell because of it?
A. I don’t — I don’t know. I mean, I wasn’t looking — I mean I didn’t look down. I don’t know.
Q. As far as you know, you just mis-stepped, and that’s what caused the fall?
A. I don’t know how the fall occurred. I really don’t.
¶ 6 The trial court denied Claimant’s request for benefits. Citing
American Management Systems, Inc. v. Burns,
¶ 7 Claimant appealed to a three-judge panel, which, with one judge dissenting, determined that the trial court’s order was neither contrary to law nor against the clear weight of the evidence and, therefore, should be affirmed. Claimant now seeks review in this court, asserting that the lower court’s order is erroneous as a matter of law.
¶ 8 Generally, the issue of whether an injury arises out of and in the course of the claimant’s employment is a question of fact for the Workers’ Compensation Court, and the any-competent-evidence standard of review applies.
City of Edmond v. Monday,
*877
¶ 9 “Oklahoma’s jurisprudence has long recognized that a compensable work-related injury must
both
(1) occur
in the course
o/and (2)
arise out
o/the worker’s employment.”

¶ 11 Generally, injuries sustained while going to and coming from work, when occurring on employer premises, have been deemed to have arisen out of and in the course of employment.
Fudge,
¶ 12 In
Corbett v. Express Personnel,
[Corbett] left his assigned station at an employer-designated locale, started his motorcycle, and was attempting to pull out of the parking lot when he lost control of the vehicle and hit a fence upon the premises. According to his testimony, his departure occurred “just before lunch started.” His undisputed purpose for the trip was to do personal business with his bank.
Id.
at ¶ 4,
¶ 13 However, the court in
Corbett
also noted that, “[w]hen they occur on premises owned or controlled by the employer, injuries sustained by an employee
while go
*878
ing to or from work
may be compensable ... if ... the claimant’s employment is shown to have a connection to the causative risk encountered.”

at ¶ 8,
¶ 14 One of the cases cited by the
Corbett
court in footnote 7 is
Max E. Landry, Inc. v. Treadway,
¶ 15 In the instant case, Claimant was arriving to begin her work day when she fell and injured herself on the stairway. According to
Corbett
and the other authorities set forth above, this injury, which occurred on Employer’s premises when Claimant was reporting for work, clearly arose out of and in the course of Claimant’s employment. Thus, the lower court’s finding that Claimant’s injury did not arise out of and in the course of her employment is erroneous as a matter of law.
See Brazeal v. Citgo Petroleum Corp.,
¶ 16 Despite the decision in
Corbett,
Employer urges us to conclude that the order denying compensation was not erroneous and that use of the “increased risk test,” as applied in
Odyssey/Americare of Oklahoma v. Worden,
¶ 17 Here, however, Claimant was on Employer’s premises, climbing a stairway to begin her work, and the use of the stairway was acquiesced in by Employer. Under those circumstances, as explained by the court in
Corbett,
¶ 18 Based on the foregoing rationale, we find Claimant’s injury to be compensable. The decision of the three-judge panel is reversed. The cause is remanded for further proceedings.
¶ 19 REVERSED AND REMANDED FOR FURTHER PROCEEDINGS.
