Various statutory bodies across the globe are focusing on standardized assessment and evaluation process. Engineering graduate should gain specific sets of skills in cognitive, psychomotor and affective domain during the years of graduation. Accreditation process is to realize the valueaddition in transforming students admitted to the program into capable technocrats. Precise assessment and attainment of POs is a key factor in the accreditation process. As of total twelve POs recommended by NBA, India, majority of engineering institutes focus on assessment of four POs that belong to cognitive domain only. Direct assessment of cognitive domain is possible with conventional tools as it has proved its validity since ancient time with conventional examination pattern. For remaining eight POs, four in affective and psychomotor domain each; various assessment tools, it's methodology of assessment, authenticity, fractional weightage are required to arrive at realistic value of attainment for concern outcomes. This paper focuses on various new assessment tools and diverse formulae for calculation of attainment value of various POs come under the affective and psychomotor domain for more realistic number. © 2018 IEEE.
