<![CDATA[Students' readiness to pursue higher education is one of the key factors influencing academic success during the transition to tertiary education. However, the availability of College Readiness measurement instruments developed based on the cultural context and characteristics of Indonesian students remains limited. This study aimed to develop a College Readiness Scale for senior high school students based on the Social Cognitive Career Theory (SCCT). The study employed a quantitative approach using a psychological scale development method involving 204 senior high school students from various regions of Indonesia. Content validity was assessed using Aiken’s V. Construct validity was examined using Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). The results showed that the College Readiness Scale demonstrated good validity and reliability. The EFA identified three main factors, namely goal orientation, academic self-efficacy, and internal barriers, with factor loadings ranging from 0.506 to 0.887. The CFA indicated that the model achieved an acceptable fit (RMSEA = 0.075, SRMR = 0.068). Furthermore, the reliability analysis yielded McDonald’s ω and Cronbach’s Alpha coefficients of 0.941, indicating excellent internal consistency. Therefore, the College Readiness Scale is considered suitable for measuring the readiness of senior high school students to pursue higher education. Abstrak Kesiapan siswa dalam melanjutkan pendidikan ke perguruan tinggi menjadi salah satu faktor penting yang mempengaruhi keberhasilan akademik di masa transisi menuju pendidikan tinggi. Namun, hingga saat ini ketersediaan instrumen pengukuran College Readiness yang dikembangkan berdasarkan konteks budaya dan karakteristik siswa di Indonesia masih sangat terbatas. Penelitian ini bertujuan untuk mengembangkan College Readiness Scale bagi siswa SMA/Sederajat berdasarkan Social Cognitive Career Theory (SCCT). Penelitian menggunakan pendekatan kuantitatif dengan metode pengembangan alat ukur psikologi terhadap 204 siswa SMA/Sederajat dari berbagai wilayah di Indonesia. Validitas isi diuji menggunakan Aiken’s V. Validitas konstruk diuji menggunakan Exploratory Factor Analysis (EFA) dan Confirmatory Factor Analysis (CFA). Hasil penelitian menunjukkan bahwa College Readiness Scale memiliki validitas dan reliabilitas yang baik. EFA menunjukkan terbentuknya tiga faktor utama, yaitu orientasi tujuan, keyakinan akademik, dan hambatan internal, dengan factor loading berkisar antara 0,506 hingga 0,887. CFA menunjukkan model memiliki kesesuaian yang memadai (RMSEA = 0,075, SRMR = 0,068). Adapun, hasil uji reliabilitas menunjukkan nilai McDonald’s ω dan Cronbach’s Alpha sebesar 0.941, yang mengindikasikan konsistensi internal sangat baik. Dengan demikian, College Readiness Scale dinilai layak digunakan untuk mengukur kesiapan siswa SMA/Sederajat dalam melanjutkan pendidikan ke perguruan tinggi.]]>
