 \nAs of June 1, 2008, a revised Certified Horticultural Technician (CHT)– maintenance and installation exam will be given by all Provincial Associations and CNLA to all new and existing candidates.  \nReasons for Change  \nFor the past two years, CNLA and PLANET’s International Certification Council (ICC) Test Revision Committee has been working to resolve the low pass rates by making sure the test is really testing the right things (occupational validity) and to ensure the test is legally defensible (which is important for any certification program) .  \nThis work has been an industry-driven effort. It began with a group of industry experts who identified what a landscape technician really does. They also listed the all the minimum standards and level of knowledge an individual needs to perform his or her job. The final result of this work is a document called an Occupational Analysis (OA) . It gives a description of all the minimum standards required and knowledge and individual must have in order to meet certification requirements. Finally, it verifies that these standards have been established through a scientific process. The OA is the foundation required for a valid certification program.  \nThe next step in the test revision process was to make sure that the material tested corresponded to the real-world tasks a technician performs in the workplace and that testing is an accurate measurement of the minimum standards established in the OA. For a certification test to be an accurate test of knowledge and ability, it must be “built” so that the technicians who should pass it, do pass the tests and so that the people who are not qualified, do not pass it. When a test is designed so that qualified people pass it and unqualified people do not pass it, then it is determined to be a “legally defensible” test.  \nSo, the end result is a certification exam where accuracy, appropriateness, and occupationally targeted testing are the goals. In addition, the exam will be aligned to the occupation – a critical component in any certification program. The test pass rate may rise, but that will be a result of the test being a more accurate assessment of what qualified technicians need to do and need to know in their jobs. Better scores result from testing the correct skill set for the industry, not because the exam was made easier.  \nMajor Changes to the Certification Program  \nBoth the installation and maintenance modules have been split, resulting in these four new classifications:  \n1. Softscape Installation  \n2. Hardscape Installation  \n3. Turf Maintenance  \n4. Ornamental Maintenance  \nChanges to the Certification Test  \nAlmost all of the hands-on problems that have made up the CHT test will remain in the test, but with some changes that will improve the judging process. The experience prerequisite has been changed from 2000 hours to 1000 hours. Numerous other changes will be implemented that will protect the integrity of the certification, and streamline the administration of the exam.  \n1. Written exams  \n• Common Core – The industry task force confirmed that the common elements to all industry technical certifications are based on safety, communication, motor vehicles,  \nmath, and reporting. The new common core will be written and will focus on only these areas.  \n• Comprehension – Each one of the four certifications will have a series of written exams specific to the four certifications. Some problems, such as Irrigation ID have been changed from hands-on problems to a part of this written exam. For all other problems where the judge asked questions requiring a verbal response, the verbal portion has been moved to the written exam.  \n• Calculations – Several hands-on problems involved a component where the candidate was required to do mathematical calculations. These questions will be moved to the written comprehension sections of the written exam.  \n• Written Exam Length – The length of each written exam w","cbCaipKZcDSqvViH","https://ap.wps.com/l/cbCaipKZcDSqvViH","pdf",21395,"English","# Reasons for Change\n# Major Changes to the Certification Program\n# Changes to the Certification Test\n## Written exams\n## Hands-on tests\n## Test problem deletions\n# Changes for Current CHTs","[{\"question\":\"When do the revised CHT maintenance and installation exams take effect?\",\"answer\":\"The revised CHT maintenance and installation exam is given starting June 1, 2008.\"},{\"question\":\"Why is the certification exam being changed?\",\"answer\":\"Changes are designed to address low pass rates by ensuring the test measures the right occupational competencies and remains legally defensible.\"},{\"question\":\"What are the four new CHT classifications after splitting the modules?\",\"answer\":\"The four new classifications are Softscape Installation, Hardscape Installation, Turf Maintenance, and Ornamental Maintenance.\"}]","Certification is Changing! - March 2008 | PDF",1790042606]
