Traditionally, attention focuses on whether assessments are reliable and valid. In practice, educational measurement is largely concerned with the analysis of data from educational assessments or tests. Typically, this means using total scores on assessments, whether they are multiple choice or open-ended and marked using marking rubrics or guides.
Again, the motive here was to standardize educational outputs and faculty workloads. Cooke established the collegiate Student Hour as "an hour of lecture, of lab work, or of recitation room work, for a single pupil" [3] per week (1/5 of the Carnegie Unit's 5-hour week), during a single semester (or 15 weeks, 1/2 of the Carnegie Unit's 30-week ...
Summative assessment is used as an evaluation technique in instructional design, It can provide information on the efficacy of an educational unit of study. Summative evaluation judges the worth or value of an educational unit of study at its conclusion. Summative assessments also serve the purpose of evaluating student learning.
Educational measurement is a process of assessment or an evaluation in which the objective is to quantify level of attainment or competence within a specified domain. See the Rasch model for measurement for elaboration on the conceptual requirements of such processes, including those pertaining to grading and use of raw scores from assessments.
CBM began in the mid-1970s with research headed by Stan Deno at the University of Minnesota. [1] Over the course of 10 years, this work led to the establishment of measurement systems in reading, writing, and spelling that were: (a) easy to construct, (b) brief in administration and scoring, (c) had technical adequacy (reliability and various types of validity evidence for use in making ...

Units of measurement are generally defined on a scientific basis, overseen by governmental or independent agencies, and established in international treaties, pre-eminent of which is the General Conference on Weights and Measures (CGPM), established in 1875 by the Metre Convention, overseeing the International System of Units (SI).
In 1948, the 9th CGPM commissioned a study to assess the measurement needs of the scientific, technical, and educational communities and "to make recommendations for a single practical system of units of measurement, suitable for adoption by all countries adhering to the Metre Convention". [36]
