In 1997, the legislature raised the cap on charter schools to 50. There is no statutorily established minimum age for admission to kindergarten, although most districts only admit students who are at least 4 years and 9 months by the start of school. Charter schools must submit their minimum age requirement for kindergarten to the Department of Education for approval.
Liability is legal responsibility.
It is based on a duty owed by one to another. Liability can apply to a person, a collection of persons, a corporation, a municipality, another governmental entity, or some or all of the above. Sometimes a law establishes a duty, sometimes a judicial decision notes the existence of a duty that had been heretofore considered common sense. If it is a law that establishes the duty, then one looks at the terms of the law and how those terms are defined within that law or in some other reasonable place. Generally, one who undertakes any task owes a duty to others to perform that task in a reasonable manner.
