Juvenile's have the same rights when taken into custody as adults do. Namely:
The right to remain silent
The right to an attorney, who will be provided by the court if the parents cannot afford one
Whatever they say to a Juvenile Officer may be used against them in their court proceedings
Any statements made to law enforcement may be used later if they are prosecuted in adult criminal court
The right to have a parent or guardian present during questioning
The right to stop talking and have questioning stopped at any point
Law enforcement must make every reasonable effort to contact a parent or guardian. If they wish to wave the right to an attorney or to have a parent or guardian present, a parent or guardian has the right to discuss it with them first. A minor may only be held for up to 24 hours, excluding weekends and legal holidays, unless the court orders a longer detention. Similar to a criminal trial, a juvenile has a right to a lawyer at an adjudicatory hearing and does not have to testify.
