If it's a big concern, set up a meeting with the parents. Reinforce the importance of a well-rounded person and explain the different types of intelligence.

I think it depends on the situation and the way the parents are saying it. If it is excitement that the child is considered gifted, cool. If it's coming from a place of "you need to score as gifted, or else..." type of situation, I would consider it bad parenting. Placing academic success in such a place of importance can really negatively affect a child for their whole lives, feeling like if they perform as anything less than gifted, they have failed. I think it should be more of a "do your best" approach, but that is just me.

This really needs to be looked at on a case-by-case basis. Some parents just see that their child is bored, doing very well, and is very intelligent. They might want to take every opportunity to encourage that, so their child has good prospects in the future. It might also be what you are thinking, that they are measuring their child against a high standard and expect too much from them. Ask some other professional educators at your school their opinion (maintaining confidentiality of course) and take what they say into consideration. But if the student is truly intelligent enough for gifted, they might do better there regardless of what their parent's intention was.

This is bad parenting to me. I think a good parent should motivate their student to just try their best, not be the best. Putting this much pressure on such a young student may stress the student out when it comes to getting good grades for the rest of their school years.

I would not say that it is bad parenting, because some students may thrive under this kind of pressure. However, being gifted is not the determining factor of intelligence. So, placing pressure on students to be gifted, if that is not the students' desire and pushes them out of their comfort zone in a negative way, is not okay.

I do not think this is bad parenting, usually parents can tell that their child is gifted on the daily and they just want them to be admitted into the best programs an school that they can be because they deserve it.
