Alto is properly the term for the second top part in four-part mixed-voice vocal writing. Applied to voices it means no more than can muddle their way through the alto part, which is not saying a whole lot, because the alto part is notoriously mind numbing (not that itâs not an essential part of the whole, or that weâre not grateful for the people who deal with it).
Longitudinal data system. Longitudinal data system is a data system capable of tracking student information over multiple years in multiple schools. The term appears in Federal law of the United States to describe such a system. Federal funding is provided to aid the design and implementation of such systems.
Metric Definitions. Core Agencies and Statewide Longitudinal Data Systems: We designated four state agencies as âcore agenciesâ within Statewide Longitudinal Data Systems: Early Learning, K-12, Postsecondary, and Workforce. We then defined a Statewide Longitudinal Data System as one with formal connections across two or more of these core agencies. States were required to include at least two of these core agencies in their data systems to be designated as having established an SLDS.
