description: Low mathematics achievement among some senior high school students is often not  identified at an early stage due to the lack of systematic and standardized diagnostic  instruments. Therefore, this study aims to develop a Cognitive Diagnostic  Mathematics Test Instrument as an early identification tool for slow learners. The  development followed the Four-D Model, consisting of the following stages: (1) test  specification formulation, (2) initial item construction, (3) limited trial, (4) item  revision, (5) field testing, (6) technical analysis, (7) final instrument development,  and (8) printing and distribution. Content validity was assessed using Aiken’s V  index, which showed that all items demonstrated good validity (V ≥ 0.80).  Readability testing and item analysis based on Classical Test Theory were  conducted during the limited trial phase involving 40 students from SMAN 3 Kota  Serang. The results were used to revise the items prior to field testing with 886  students from four senior high schools in Jakarta, Kota Tangerang, and Kabupaten  Serang. The two-parameter logistic Item Response Theory (IRT 2-PL) analysis  indicated that most items had high discrimination and appropriate difficulty levels  for diagnostic purposes. To ensure construct validity, Kaiser-Meyer-Olkin (KMO)  and Confirmatory Factor Analysis (CFA) were performed. The KMO results  demonstrated that the data met the required sampling adequacy, with overall MSA  values ranging from meritorious to marvelous (0.72–0.93). Meanwhile, CFA results  revealed that most subdomains fit the recommended goodness-of-fit indices (CFI,  TLI ≥ 0.90; RMSEA ≤ 0.08; SRMR ≤ 0.08), supporting the theoretically established  factor structure. The final instrument consists of 105 test items (113 sub-items)  distributed across five major domains: number, algebra, measurement, geometry,  and data analysis and probability. The implementation trial involved 300 students  from SMA Garuda Cendekia to assess the instrument’s accuracy. The analysis  indicated that a cut-off score of ≤ 85 yielded a sensitivity of 80%, specificity of 65%,  and overall accuracy of 72%. Students scoring ≤ 85 are classified as low-achieving  and potentially slow learners, further divided into types 1, 2, and 3. The  implementation results showed that type 3 achieved 100% accuracy, type 2  achieved 71%, and type 1 achieved 83%. Thus, the Cognitive Diagnostic  Mathematics Test Instrument developed in this study has been proven to be valid,  reliable, and effective for the early identification of slow learners.
