An active clearance is one in which the candidate is presently eligible for access to classified information. A current clearance is one in which a candidate has been determined eligible for access to classified information but is not currently eligible without a reinstatement.
The NCTM Standards evolved over several years, beginning with the 1980 report An Agenda for Action (NCTM, 1980), an important precursor to the NCTM Standards documents. A set of events and circumstances took place in the 1980s that spurred the need for standards and for national direction in mathematics education.
In this respect, those content standards which set an expectation of understanding are potential points of intersection between the Standards for Mathematical Content and the Standards for Mathematical Practice. The Standards for Mathematical Practice describe varieties of expertise that mathematics educators at all levels should seek to develop in their students. These practices rest on important âprocesses and proficienciesâ with longstanding importance in mathematics education. The first of these are the NCTM process standards of problem solving, reasoning and proof, communication, representation, and connections.
