According to the U.S. <a href="/wiki/National_Council_on_Measurement_in_Education" title="National Council on Measurement in Education">National Council on Measurement in Education</a>, a certification test is a credentialing test used to determine whether individuals are knowledgeable enough in a given occupational area to be labeled "competent to practice" in that area.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Types">Types</h2></div> <p>One of the most common types of certification in modern society is <a href="/wiki/Professional_certification" title="Professional certification">professional certification</a>, where a person is certified as being able to competently complete a job or task, usually by the passing of an examination and/or the completion of a program of study. Some professional certifications also require that one obtain work experience in a related field before the certification can be awarded. Some professional certifications are valid for a lifetime upon completing all certification requirements. Others expire after a certain period of time and have to be maintained with further education and/or testing. </p><p>Certifications can differ within a profession by the level or specific area of expertise to which they refer. For example, in the IT Industry there are different certifications available for <a href="/wiki/Software_tester" class="mw-redirect" title="Software tester">software tester</a>, <a href="/wiki/Project_manager" title="Project manager">project manager</a>, and <a href="/wiki/Software_developer" class="mw-redirect" title="Software developer">developer</a>. Also, the <a href="/wiki/Joint_Commission_on_Allied_Health_Personnel_in_Ophthalmology" title="Joint Commission on Allied Health Personnel in Ophthalmology">Joint Commission on Allied Health Personnel in Ophthalmology</a> offers three certifications in the same profession, but with increasing complexity. </p><p>Certification does not designate that a person has sufficient knowledge in a subject area, only that they passed the test.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> This of course apples only to exam-based certifications.

That is <a href="/wiki/Licensure" class="mw-redirect" title="Licensure">licensure</a>. Usually, licensure is administered by a governmental entity for public protection purposes and a professional association administers certification. Licensure and certification are similar in that they both require the demonstration of a certain level of knowledge or ability. </p><p>Another common type of certification in modern society is <a href="/wiki/Product_certification" title="Product certification">product certification</a>.
