"Scheduled to September" vs. "scheduled in September"

Question

• She is qualified to attend the test being scheduled [to/in] September.

Which is right?

Answer 1

You can use "scheduled for [time period]", but not "scheduled to [time period]".

The expressions "scheduled to take place in [time period]" or "scheduled to happen in [time period]" are acceptable, too.

"Scheduled in [time period]" is sometimes seen, but I'm inclined to read this as elliptic/short for "scheduled to take place in [time period]".
