A friend shared list of teachers from Chikun LGEA who scored 75 and above in the Kaduna 'Competency Test'. The list, a PDF document was converted to MS Excell file, and voila! 50 names were found to be duplicated. For instance, these names were repeated in the list: Ja'afar Babajo appeared on S/No. 262 also 272, Ibrahim Makama 352/381, Thamar Esther Jiko 374/455, Tambaya Barau 326/508, Queendaline Onuoha 524/556, Zainab Buba 299/568. It is claimed that the name Alalu Mohammed does not exist; but it was nevertheless duplicated. Now, if errors and duplications can be discovered on the list of 'competent teachers' how credible and reliable is the much bigger data of 22k failed teachers? Your guess is as good as mine.
