The certification of textbooks by the Nigerian Educational Research and Development Council (NERD) costs N300 per page, and four copies must be submitted for assessment, which occurs irregularly and can take months or years. While NERDC approval grants access to Federal Government schools, getting state-level approval requires further steps across Nigeria's 36 states. Despite these procedures, unapproved textbooks lacking ISBN numbers infiltrate schools through corruption, bypassing regulations. Efforts to tackle piracy and enforce the use of approved books remain ongoing and vital for the education system's integrity.

The cases of corruption in the education sector in Oyo State are ranging from reports of school administrators collecting money, students sitting mock exams, officials asking for grants from principals before distributing the school materials the government purchased for students to receiving money from teachers to deploy them to preferred areas. The governor announced that dismissal and prosecution awaited anyone who sabotaged government efforts through corrupt practices.
