This app allows you to conveniently check your business English speaking skills! ■Overall evaluation of PROGOS The Common European Framework of References for Languages (CEFR) places a great deal of importance on "What can I do with the language?". Therefore, the overall evaluation of PROGOS takes into account the six qualities of speech (range of vocabulary, accuracy, fluency, interaction, coherence, and phonology) as well as the degree to which communicative objectives are achieved. It is not a simple sum of vocabulary and pronunciation assessments, but a measure of practical communication skills. ■Analytical Evaluation 6 analytical aspects defined by the CEFR. (1) Range Knowledge of grammar, sentence structures, vocabulary, and phrases. (2) Accuracy Correct use of grammar, vocabulary, etc. (3) Fluency Fluent and smooth speaking. (4) Interaction Ability to start, end and / or maintain a conversation. (5) Coherence Organization of speech and logic. (6)Phonology Intelligible pronunciation, intonation and stress. The following are also included in the feedback sheets: ・ The Can-Do descriptor of the CEFR level result. ・ General feedback and advice on how to improve speaking skills by one level. ▶PROGOS Strengths ■Convenience A 20-minute test that can be taken anytime, anywhere online.
