Vaccinations offer protection from common infectious diseases. Colorado law requires every child who is attending school in the state to present an up-to-date certificate of immunization. State law also allows for a student to be exempt from the immunization requirements for medical reasons, religious beliefs, or personal beliefs.
In lieu of issuing bonds, or using another form of long-term debt, the state often uses a form of lease-purchase agreement called certificates of participation (COPs) to finance the construction of its new facilities. A certificate refers to an investor's proportionate interest in the state's lease payments. COPs give the state the flexibility to build capital facilities even when funds are not available to pay for projects on a pay-as-you-go basis.
