Finding a shy child in school isn't that hard to do, just like there are a variety of personalities in any adult's workplace. Particularly in case the child's teacher reports good behavior in class, many times, shyness is just shyness and is not cause for concern. What we think may be simple shyness may actually be an internalizing behavior that might be a sign of depression. it has been well documented that shyness and like behaviors, such as social withdrawal, are actually overshadowed by externalizing behaviors that are disruptive or aggressive -- especially in schools in children for whom this is true. That is, what's going on inside is masked by what we can actually witness. Depression child may not act out in this way, the combination may be a sign that there is reason for concern though a shy. That is hard to say. According to the American Academy of Pediatrics, approximately 3% of children have a depressive disorder.  The majority show some signs of social or academic withdrawal while not all depressed children have internalizing behaviors. Girls are reported to have more internalizing behaviors than boys in addition to this. Dr. Leslie D. Leve and colleagues, who published a study of the topic in the Journal of Abnormal Psychology in 2005, identified four factors that may contribute to a child's internalizing behaviors.

Shyness in school may be a sign of depression

They found that children who had depressed mothers, were exposed to harsh discipline and/or parental fighting, and who had a more shy and fearful temperament were more likely to display internalizing behaviors than those who did not. Of course, these findings do not suggest that these situations apply to all children with depression and/or internalizing behaviors. Children who are quiet are often considered well-behaved as compared to their noisy and disruptive classmates in a busy classroom. Something that likely escapes the capacity of what a busy teacher can investigate is whether a child is actually quiet because she's well-behaved or because she's too shy or fearful to speak. Dr. Leve's study showed that teachers reported higher rates of disruptive or externalizing behaviors in the classroom than parents reported of their own children -- so yes, a teacher may indeed ID a problem, particularly since it's clear how disruptive externalizing behaviors can be to a classroom. Children with disruptive behaviors are more likely to require discipline and thus be referred to a school counselor or psychologist, or for outside treatment. That said, there is no guarantee. Again, though poor behavior is a particular cause for concern in a shy child, not every shy child who is depressed will act out in this way. Furthermore, shyness is not always a sign of depression.  Including the limitations of the classroom, and consult their child's doctor and/or school faculty beyond classroom teachers for insight into their child's behavior, parents should be aware of this. Children with unexplained physical symptoms tend to frequent the school nurse's office and account for a significant amount of the school's heath resources according to Robin Adair Shannon and colleagues, who published a study in the Journal of School Nursing in 2010.
