To test for the First Class license one had to have passed the exam for a Second Class license. Because it included the entire field of electronics transmission, the examination to earn the Second was generally thought of as more difficult than that of the First, which concentrated on broadcast radio and television.
The CIE recommends that "The concept of correlated color temperature should not be used if the chromaticity of the test source differs more than Δ uv = 5×10 −2 from the Planckian radiator." [22] Beyond a certain value of Δ uv, a chromaticity co-ordinate may be equidistant to two points on the locus, causing ambiguity in the CCT.
A computerized classification test (CCT) refers to a Performance Appraisal System that is administered by computer for the purpose of classifying examinees. The most common CCT is a mastery test where the test classifies examinees as "Pass" or "Fail," but the term also includes tests that classify examinees into more than two categories.
Another early CCTV system was installed by Siemens AG at Test Stand VII in Peenemünde, Nazi Germany, in 1942, for observing the launch of V-2 rockets. [10] In the United States, the first commercial closed-circuit television system became available in 1949 from Remington Rand and designed by CBS Laboratories, called "Vericon". [11]
The CCIE consists of a written exam and a "lab" exam (in each track). The written exam acts as a prerequisite of the lab exam and has a cost of $400 per attempt. The written exam consists of 100 questions that must be completed within 2 hours. Upon passing the written exam, the candidate has eighteen months to take the lab exam.
In psychometrics, item response theory (IRT, also known as latent trait theory, strong true score theory, or modern mental test theory) is a paradigm for the design, analysis, and scoring of tests, questionnaires, and similar instruments measuring abilities, attitudes, or other variables.
Few development initiatives have been evaluated as rigorously as CCT programs. [1] The implementation of conditional cash transfer programs has been accompanied by systematic efforts to measure their effectiveness and understand their broader impact on household behavior, [1] a marked departure from the limited attention that was paid to rigorous impact evaluations in the past.
The United States Air Force Combat Control Teams, singular Combat Controller (CCT) (AFSC 1Z2X1), are an elite special operations force (specifically known as "special tactics operators") who specialize in all aspects of air-ground communication, as well as air traffic control, fire support (including rotary and fixed-wing close air support), and command, control, and communications in covert ...
