Is she happy in K, or is she bored and frustrated? If she's happy enough, one way to ensure that you don't have any gaps would be to have her continue with K this year, and then start 2nd grade next year. You could then request materials from the school and use the summer as a chance to cover the missed material. She would also then benefit from the beginning-of-the year review period in second grade.

If you choose that route, could they confirm at the meeting that she would be eligible for the "official program" next year for second grade?
