The research focus is on the quality of speaking testing instruments for junior secondary students in West Bandung District. In general, the study aims at creating a model of Sundanise language speaking skills assessment which can provide information for schools in terms of contents, scope, delivery format and time, and can be effectively use Sundanise language teaching.

The relevance of EPBI model and field data (P-value = 0, 72541 > 0,05; RMSEA = 0,000 < 0,05; GFI = 1,70 > 0,9; AGFI = 1,43 > 0,9; PGFI = 1,37 > 0,9) reveals that the quality of speaking testing  model is fit is worth considering as an assessing instrument of junior secondary school speaking instruction as supported by theoretical concepts, expert judgment, and field tryout results., and judgment by experts, users, and practitioners shows that MPPBS model is reliable as a referred implementation model.
