The ALKAS (Asenu di Alkansadu kung Linggu Kristang na Singapura) is a diagnostic exercise administered at the end of each level of Kodrah Kristang classes to understand how learners are coping with the material in the level. The ALKAS assessments are generally offered twice yearly; once in May, and once in November. See the Schedule of ALKAS exercises for more information about when the next ALKAS exercise will be held.
