There is debate as to whether Penelope is aware that Odysseus is behind the disguise. Penelope and the suitors know that Odysseus (were he in fact present) would easily surpass them all in any test of masculine skill, so she may have intentionally started the contest as an opportunity for him to reveal his identity. On the other hand, because Odysseus seems to be the only person (perhaps excepting Telemachus) who can actually use the bow, she could just be further delaying her marriage to one of the suitors.
