calendar for NAEP assessments. Please refer to the entire assessment schedule for all NAEP assessments since 1968 and those planned through 2017. Main NAEP assessments are typically administered over approximately six weeks between the end of January and the beginning of March of every year. Long-term trend assessments are typically administered every four years by age group between October and May. All of the assessments are administered by NAEP-contracted field staff across the country. NAEP State Coordinators (NSC) NAEP is conducted in partnership with states. The NAEP program provides funding for a full-time NSC in each state. He or she serves as the liaison between NAEP, the state's education agency, and the schools selected to participate. NSCs provide many important services for the NAEP program and are responsible for: coordinating the NAEP administration in the state, assisting with the analysis and reporting of NAEP data, and promoting public understanding of NAEP and its resources New digitally-based assessments (DBA) While most NAEP assessments are administered in a paper-and-pencil based format, NAEP is evolving to address the changing educational landscape through its transition to digitally-based assessments. NAEP is using the latest technology available to deliver assessments to students, and as technology evolves, so will the nature of delivery of the DBAs. The goal is for all NAEP assessments to be paperless by the end of the decade. The 2011 writing assessment was the first to be fully computer-based. Interactive Computer Tasks (ICTs) In 2009, ICTs were administered as part of the paper-and-pencil science assessment. The computer delivery affords measurement of science knowledge, processes, and skills not able to be assessed in other modes. Tasks included performance of investigations that include observations of phenomena that would otherwise take a long time, modeling of phenomena on a very large scale or invisible to the naked eye, and research of extensive resource documents. Mathematics Computer-Based Study This special study in multi-stage testing, implemented in 2011, investigated the use of adaptive testing principles in the NAEP context. A sample of students were given an online mathematics assessment which adapts to their ability level. All of the items in the study are existing NAEP items. Technology and Engineering Literacy (TEL) Assessment The TEL assessment framework describes technology and engineering literacy as the capacity to use, understand, and evaluate technology as well as to understand technological principles and strategies needed to develop solutions and achieve goals.
