The 41-year-old was led by police out of Helena school on Tuesday and was remanded in custody on Friday by Skaraborg district court.
He has been suspended from the school without pay and a tribunal will begin next week which is expected to result in his dismissal.
While admitting that he has engaged in sexual activities with a student, he denies the other charges of which he is accused.
According to a TV4 report, the teacher began having sexual liaisons with a female pupil at the beginning of the year.
When the allegations recently came to light, it was suspected this was not the first time he had forged a sexual relationship with a student.
Last week, Anna Sundström, school chief for Skövde municipality took action and reported the teacher to the police.
“I fail to see any extenuating circumstances,” she told TV4. “Unfortunately, this seems to be a case that has repeated itself. It was only last week when the real seriousness of what has happened was revealed.”
The school is now working with teachers and students and three counsellors have been put in place to offer one-on-one discussions.
“This is a very unusual situation,” Bertil Lönn, headmaster of Helena school, told TV4.
“Naturally we have to discuss the issue but we have not yet confirmed where we go from here.”
