The Word Engine is a patented new approach to knowledge assessment and knowledge acquisition. The Word Engine helps people get ahead fast by identifying and rapidly teaching the most important words and facts that each learner is missing for their specific career or standardized academic test such as the SAT, GRE, TOEIC, TOEFL, EIKEN, GAOKAO etc. The Word Engine supports teachers and business managers with diagnostic reports about each student and employee. The Word Engine identifies each learner's current level of subject comprehension and supports their learning progress all the way until completion. Concise progress reports detail time-on-task, new words learned, individual and organizational comprehension ability for each subject. Word Engines are typically sponsored by universities, businesses and publishers and used to test and teach the specific vocabulary (and factual knowledge) that is required to comprehend specific academic and vocational subjects. The Word Engine is operated by the Lexxica Corporation. Lexxica offers a large menu of standard courses for the most popular academic and vocational tests. Lexxica is also capable of quickly creating custom courses for any subject matter.
