Abstract The 11 taxa of self explaining its actualization through Quranic Orientation Scale (QOS) were revised and expanded. Along with a demographic scale, the QOS was administered to 1123 grade 4 senior high school (G4SHS) students among whom 147 took a schema-based close multiple choice item language achievement test (S-Test) as well. The responses on the QOS were then subjected to factor, reliability and correlational analyses by resorting to Varimax with Kaiser Normalization, Cronbach Alpha and Pearson product-moment correlations. The responses were also correlated with the students’ scores on the S-Test. The results showed that the QOS and its seven underlying factors measure eight taxa of self actualization called monotheists (MTs), fake monotheists (FMTs), doubtful monotheists (DMTs), polytheists (PTs), self-theists (STs), wise theists (WTs), emotional theists (ETs) and cognitive theists (CTs). Only did the taxa of MTs and FMTs represented by the QOS and its first factor associate with language achievement measured by the S-Test. Since these two taxa also dealt with health, their correlation with the S-Test showed that there is a significant relationship between G4SH students’ actualization of their selves as MTs and FMTs, their language achievement and health. A textual analysis of representative medical, psychiatric, psychological and religious textbooks was also run by resorting to schema theory to discuss and explain selves actualized by MTs and FMTs through health.
