There has always been an attempt to figure out why some people do better in school than others. Is it due to financial stability? Is it attributed to parents ' own success as students? Very importantly, one 's birth order plays a role in one 's school achievement.

School achievement is gauged by how far one goes in his or her education, starting from grade school, all the way up to graduate school. Before getting into the developmental stages across the life span and in the interest of time, I will only be discussing birth order in terms of the oldest child, middle child, youngest child and only child because configurations of five or more children occur only in 10% of the families with children. The average family in the U.S. has three (Toman, 1976). Also, I will be dividing the developmental stages into 3 stages: childhood, adolescence and adulthood.
Childhood (Ages 1-12) The firstborn child is likely to have intensified feelings of power and superiority, high anxiety, and overprotective tendencies (Feist & Feist, 2002). The firstborn children usually have a close relationship with the parents than laterborn children.

For a while, these children are only children until a younger brother or sister is born. They experience a traumatic dethronement, which may development resentment towards the new baby.
