My question involves a child custody case from the State of: Ohio
Relevant Background: parents have shared parenting agreement where both legal and physical custody is 50/50. Parents live in separate school districts and "parent a" has residential parent for school placement purposes.
Situation: parent a has done ample work with the child to get the child ahead academically. Parent b has done very little but sees child is ahead. The child dislikes school work and hates being challenged or having to think. Parent b wishes to try and place the child in a gifted program. We will give parent b the benefit of the doubt and say it is to help the child succeed (as opposed to bragging rights since parent b has been bragging since kindergarten that the child is gifted). Parent a sees the child dislikes school work as it is and in an attempt to salvage whatever small portion of liking school remains wishes to keep the child in standard classes. Because this issue was brought up last year (a year before they test), parent a has largely stopped trying to get the child ahead and already this year the child displays some difficulty doing standard level homework, which reinforces parent a's theory that the child only appeared gifted because of hard work to get ahead (the child is without a doubt a talented student, parent a just does not believe a gifted program is the correct decision for the child's personality.
Since the child is still a fair ways ahead of her class-especially in reading-it is still very possible for her to score well on the test. Should that happen, agreement between the parents is unlikely and of course there can't be a compromise-the child will either be in a gifted program or not-child cannot be "partly" in a gifted program after all.
Question: in the event that the parents cannot agree on this issue, would the ultimate choice go to the parent with residential custody for school purposes? If not then what is the likely result?
