Kemampuan berpikir kritis digital menjadi fenomena baru yang penting dieksplorasi namun masih memilki keterbatasan dalam instrumentasi khususnya untuk mendukung kesiapan karier siswa SMK, Penelitian ini bertujuan mengembangkan dan memvalidasi instrumen kemampuan berpikir kritis digital berbasis indikator Watson-Glaser melalui pemodelan Rasch. Penelitian dilaksanakan pada siswa kelas XI SMK di Jawa Timur dengan desain survei kuantitatif observasional. Instrumen yang dikembangkan terdiri dari 44 butir pernyataan dengan aspek argumentasi, asumsi, deduksi, interpretasi, dan kesimpulan. Analisis Rasch dilakukan menggunakan aplikasi Winsteps 3.73 untuk menilai validitas, reliabilitas, serta kualitas item. Hasil penelitian menunjukkan instrument memiliki keberterimaan pada kategori baik mendekatai ideal berdasarkan penilaian statistik dan Rasch. Temuan ini mengindikasikan bahwa instrumen yang dikembangkan memiliki kualitas item yang sangat baik dan layak digunakan oleh guru bimbingan dan konseling dalam mengukur kemampuan berpikir kritis digital siswa SMK sekaligus mengakomodasi sumber data dalam pengembangan program layanan bimbingan dan konseling karier di SMK. Abstract. The trend of measuring critical thinking skills of vocational high school students has increased in the last 5 years. Digital critical thinking skills are a new phenomenon that is important to explore but still has limitations in instrumentation, especially to support career readiness of vocational high school students. This study aims to develop and validate a digital critical thinking ability instrument based on Watson-Glaser indicators through Rasch modeling. The study was conducted on 11th grade vocational high school students in East Java with an observational quantitative survey design. The developed instrument consisted of 44 statement items with aspects of argumentation, assumptions, deductions, interpretations, and conclusions. Rasch analysis was carried out using the Winsteps 3.73 application to assess validity, reliability, and item quality. The results showed that the instrument had an acceptability in the good category approaching ideal based on statistical and Rasch assessments. These findings indicate that the developed instrument has very good item quality and is suitable for use by guidance and counseling teachers in measuring digital critical thinking skills of vocational high school students while accommodating data sources in developing career guidance and counseling service programs in vocational high schools.]]>
