Warren Fertig, who is 72, was supposed to stand trial this week in Red Deer.
But court was told Tuesday that a resolution had been reached in the case.
The allegations of rape and sexual intercourse with an underage student dated back to when Fertig was a teacher in the 1970s.
He was charged in September 2011 after a woman came to police and said she had sex with Fertig when she was between 12 and 15 years old.
The defence requested a forensic assessment and sentencing is expected to take place on Jan. 17.
