Hello and thank you for responding. With regards XXXXX XXXXX school issues, schedule a conference with the teacher. Voice your concerns. The teacher needs to make a concentrated effort to make sure that she is included in school activities. The teacher should give her some leadership roles as well. Your daughter needs to develop greater self esteem and confidence. If she is not involved in any sports, get her involved in that as well. That will foster a sense of team building and make her feel important as she is a part of a group. If she is truly an introvert and you see very little hope that she will change, you may want to seek outside professional counseling in which your daughter can receive on going intervention strategies to enhance her sense of belongingness.
Hope this provides you with some insight. Have a great day!!!
