Which form is used for requesting approval of school attendance for school children over 18 only?

The correct form for requesting approval of school attendance for school children over the age of 18 is indeed the 21-674. This form is specifically designed to provide the necessary documentation to determine the eligibility for educational benefits for dependents who are 18 years old or older. The data collected through this form helps in ensuring that benefits are appropriately allocated based on the educational status of the dependent.

By focusing on school children who have reached 18, the 21-674 also reflects the specific concern of qualifying individuals who may still be engaged in their education and eligible for certain veterans' benefits. This aligns with the regulations laid out by the Veteran Affairs to support the educational pursuits of the children of veterans as they transition into adulthood.

The other forms mentioned serve different purposes. For instance, some pertain to various types of benefit claims or requests that do not specifically address the criteria for students over the age of 18. Therefore, it's important to use the correct form to ensure compliance with the criteria set by the Veteran Affairs.
