Educators were reminded that they’re obliged to teach nor to judge, that it is their duty to fill in the gap of their students rather than to apprehend them learn what they have plotted. This study gives lights behind the dark sides of understanding against the Learners capacity towards the Learning standards as structured, the study conquered the traditional concept of evaluating the performance of the Students the way they were judged due to their limitations, the Learners, Teachers and School Administrators were enlightened about their perspective on Quality Education that this is coherent to quality teaching which is gearing to an excellence learning- process, appropriate performance assessment, and standard grading system. Nevertheless parties concerned should familiarize: Philippine Teaching-Learning Standards; 21st Century of Education; Learning Motivations; and Students Performance Assessment; and showcase a precedence for uncertainties, complaints and grievances in accordance to the law (de jure), cited decrees: Professional Code of Ethics; Philippine 1987 Constitution; and Magna Carta for Teachers. This study also clarify paradoxical issues: first, what are the bases of Teachers in failing his students; and second, what are the causes of the Learner’s incomplete (INC) grades. It is also presumptuous and confirmatory to holds the following hypotheses: Ho: Teachers bases in failing his students don’t correlate to grades criterion, Ha: Teachers criterion in giving grades is based on his/her personal assessment. Instruments were developed: Survey Questionnaire on Teachers’ grading system; Survey questionnaire on Teacher’s Quality Teaching and Quality Assessment and Template in tracking the records on Frequencies and Percentages of Students with Failing and Incomplete Grades.
