I would also appeal.

As for the reasons, those you've given may be important to a family but not to a school.
You might want to consider that research shows ALL children need and benefit from having:
- appropriate curriculum placement, to provide a challenge in their zone of proximal development (ZPD),
- intellectual peers.
For typical children, these needs may be met in the typical classroom, however for gifted pupils, special planning may be needed to provide the challenge level of curriculum and intellectual peers.

Here are some links to old posts, which may help you plan your presentation as you advocate to change the school's placement decision for your daughter.

IMO, a reading list is great as long as you are emphasizing that the reading selections and choices are the child's own, and that she enjoys her reading.

In regard to Tiger parenting, it is important that children do not develop an idea that they must perform at a certain level to please their parents. They must not perceive a need to engage in sibling rivalry to compete for the parents' attention, approval, or acceptance. In other words, a parent would want a child to know that it is fine, natural, normal, and expected that one may be more accomplished in an area and have a lower level of achievement in another. A focus on personal best may help a child develop resilience. A healthy attitude reminds us that in each setback, disappointment, or failure, a person can learn something positive. If a person does not learn to embrace this, they may, unfortunately, develop an unhealthy fear of failure... sense of perfectionism... refusal to try anything they are not guaranteed to be instantly successful with... and this results in procrastination and underachievement.
