I read a science fiction novel from my junior high library, so sometime between 1974-1976 but I don’t know how old it was at the time. It was a coming-of-age story. The point of view character was a boy/young man. He and his group crashed(?)/were stranded on an alien, rocky planet. There are adults with him, but somehow he has to take charge. He encounters another human castaway/refugee, whom he takes to be another boy and who is wary of him. Turns out the other boy is a girl in disguise. They decide to cooperate. Any ideas what book this was?
Robert A. Heinlein, Tunnel in the Sky.
Could it be Tunnel in the Sky by Robert Heinlein?

No adults, but this sounds like Tunnel in the Sky by Robert Heinlein. The teens are on a school exercise to another planet, but the transport technology breaks down. The boy/girl is Jacqueline, and calls herself Jack.
Thanks for the replies. You’re all in agreement, and Heinlein sounds plausible, so I’ve requested a copy. It’ll be worth (re)reading in any case. . . .
