Kajian ini bertujuan untuk membangun dan mengesahkan instrumen Literasi Pentaksiran Guru Vokasional (VoTAL) dengan menentukan ciri-ciri psikometrik instrumen menggunakan Model Pengukuran Rasch. Proses pembangunan instrumen ini mengandungi tiga fasa iaitu fasa pembinaan, fasa pengujian dan pemurnian, serta fasa pengesahan. Fasa pembinaan melibatkan konseptualisasi, penjanaan item dan pemeriksaan kesahan kandungan instrumen. Proses konseptualisasi dan penjanaan item dilakukan menggunakan pendekatan deduktif. Pemeriksaan kesahan kandungan pula dilakukan melalui penilaian oleh 21 panel pakar dan dianalisis menggunakan nisbah kesahan kandungan (CVR) Lawshe. Fasa pengujian dan pemurnian melibatkan kajian rintis dan pemurnian item. Kajian rintis dilaksanakan di lima buah kolej vokasional melibatkan 229 guru vokasional yang dipilih menggunakan teknik pensampelan rawak kelompok berperingkat. Item-item kemudiannya dimurnikan berdasarkan kepada hasil dapatan analisis Rasch. Fasa penge.....
