Streptococcus pneumoniae can be differentiated from the viridans streptococci, some of which are also alpha-hemolytic, using an optochin test, as S. pneumoniae is optochin-sensitive. S. pneumoniae can also be distinguished based on its sensitivity to lysis by bile, the so-called "bile solubility test".

Empirical information on the achievement level of pupils/students serve as a guide for policy makers, administrators, curriculum planners, principles, and teachers, along with analysis on the performance of regions, divisions, schools, and other variables ...
