Case of Maria

Maria is a 10th grade student who has been referred to the school counselor because of her unacceptable behavior in the classroom and her poor peer relationships.

School personnel are concerned about Maria’s inability to function well in a school setting. Although she exhibits problematic behavior, it is not severe enough for suspension. Maria has an excellent vocabulary and a good sense of humor. However, she does not know how to respond to teasing or correction and seems to enjoy telling stories about how she gets back at people who offend her. In the classroom, Maria is frequently off task, asks inappropriate questions, comes unprepared, wanders about the classroom, and seeks to make herself the center of attention. Outside of the classroom, she keeps to herself, but she stands out in the crowd. Her mannerisms and dress set her apart. She appears to be preoccupied and seems to fear her parents, not wanting them to know what happens in school.

To obtain more information about Maria, the school counselor uses information related to her current grades, as well as her scores on the Wide Range Achievement Test (WRAT4).
