Emotional and behavioral disorders (EBD) is a broad category which is used commonly in educational settings, to group a range of more specific perceived difficulties of children and adolescents. Both general definitions as well as concrete diagnosis of EBD may be controversial as the observed behavior may depend on many factors.

The 5 models that are used in EBD are:

A child exhibiting one or more of the following characteristics to a marked degree for a long duration of time that adversely affects their education:

1. Difficulty to learn that cannot be explained by intellectual, sensory, or health factors.

2. Difficulty to build or maintain satisfactory interpersonal relationships with peers and teachers.

3. Inappropriate types of behavior or feelings under normal circumstances.

4. A general pervasive mood of unhappiness or depression.

5. A tendency to develop physical symptoms or fears associated with personal or school problems.

The term includes schizophrenia. The term does not apply to children who are socially maladjusted, unless it is determined that they have an emotional disturbance. Code of Federal Regulation, Title 34, Section 300.7 (c) (4) (ii)

Andrew Johnson (December 29, 1808 – July 31, 1875) was the 17th President of the United States (1865–1869). As Vice President of the United States in 1865, he succeeded Abraham Lincoln following the latter's assassination. Johnson then presided over the initial and contentious Reconstruction era of the United States following the American Civil War. Johnson's reconstruction policies failed to promote the rights of the Freedmen, and he came under vigorous political attack from Republicans, ending in his impeachment by the U.S. House of Representatives; he was acquitted by the U.S. Senate.

Johnson, born in poverty and of Scots-Irish descent, became a master tailor and was self-educated, married and had five children. He served as an alderman and as Mayor of Greeneville, Tennessee and then sat in both houses of the Tennessee legislature. He went on to spend five consecutive terms in the U.S. House of Representatives and two terms as Governor of Tennessee, all as a Democrat. His signature legislative endeavor in the state and federal arenas was passage of the Homestead Act.
