A&E test has been conducted year after year for 15 years now. You cannot just say you lack the experience… It is a given fact that the test takers need to get their A&E results early so they can process the requirements for enrolment.
Maybe you should consider localizing the assessment process so that the test would be more contextualized – using the local language and socio-economic condition of the learners so that you do not ask essay questions about agricultural concerns to ALS students in Manila and you do not ask essay questions about technological gadgets to learners who live in places that do not even have any electricity.
Localizing A&E would also allow for more authentic assessment. A farmer for example might not be able to compute abstract math problems unrelated to his craft using paper and pencil test. But if you ask him to explain and demonstrate how he computes for farm inputs, spatial requirements for planting, you might see the most elegant naturalistic and agri-based math.
It’s been proven through research that literacy (and numeracy) is context specific. You cannot decontextualized it and represent it in highly textual abstraction, otherwise you would miss its real and dynamic (functional) meaning.
