SCHENECTADY, N.Y. — Officials at an upstate New York school district say a kindergartner spent a day at the wrong school after getting on the wrong bus.

Schenectady school district officials said the series of mistakes began Wednesday morning when the 5-year-old girl boarded the wrong bus, which was driven by a substitute driver.

At the school, teachers were expecting a new first-grader and asked the girl if she was that student. The girl said she was and spent the day answering to the no-show first-grader’s name.

The mistake wasn’t discovered until the kindergartner’s mother called her school to report that her daughter didn’t get off the bus that afternoon. School officials said they located her a short time later.

The district said it’s re-examining its bus and new student procedures.
