Literacy in Nigeria, even by the sub-Saharan Africa standard, is low. Much lower is critical and digital literacy. These two aspects of literacy hold the key to national development and security. This study examined these two aspects of literacy as crucial components of the literacy programme in Nigeria. The core elements of textuality for effective interpretation were studied. The study also took a look at digital literacy as a component of Nigeria’s educational programme as a means to enhance classroom interaction and bridge some existing gaps in availability of resources and time. National development and security were seen to hinge on developing critical and digital literacy. The procedure adopted in the study was qualitative.
