Here is a great KS site on juvenile rights and responsibilities:

Here's the stuff you were looking for. The school should refer a chronic truant to the courts
By law, how many years must I stay in school?
Unless approved by the court, children between the ages of seven and 18 must attend a public or private school. This may vary if you have been identified as having a disability and are entitled to receive special services. Some school districts have specialized programs that allow students to go to school and also work during school time. There are alternative schools that have specialized policies or curriculum like a technical school.
What if I don't want to go to school?
The law requires all children in our country to go to school. In Kansas, you have to attend school until the age of 18. Schools must check to find out why you are not in school. Your parents may be held responsible for your not attending school. You may be allowed to be "home schooled" or sent to a private school approved by the state.
What happens if I skip school?
You are required to attend school. This will have a major impact on your future, and it certainly will affect your parents or guardian because they will be held responsible. The courts can be involved if you continually miss school, and your parent or guardian does not or is unable to get you back in school. Eventually, you might end up in court custody. The court would then have to decide where you would be placed so that you do attend school.
If a student misses three consecutive days, five days in a semester or seven days in a school year, the school must notify your parents. The school will also notify Social and Rehabilitation Services if you are under 13, or the county attorney if you are over 13 years of age.
