Abstract—The study aimed to determine the validity,
reliability, polarity and fitness of the items, as well as to confirm
the measurement model of Clothing Fashion Design
Competency (CFaDC). Winsteps software was used to test the
validity and reliability of the instrument, meanwhile AMOS
was used to verify the measurement model. The results show the
index of the items, the reliability of the individual (person) and
high separation of the items and individual isolation. The results
also show that the instrument is consistent, valid, stable and
reliable if being administered into another sample with similar
characteristics. Polarity items indicate that there were 4
knowledge items that measured other constructs and the items
were dropped. A total of 31 knowledge items and 16 skills items
were detected as misfit and were also dropped. Measurement
model was fitted to the data and was accepted based on the
suitability index (Fit Indices) that has been achieved, namely:
CMIN
χ ² = 1306,979, with degrees of freedom (df) 680,
CMIN/df = 1.922 (< 5.0), CFI = 0.941 (> 0.90), IFI = .941 (> 0.90),
TLI = 0.935 (> 0.90) and RMSEA = 0.053 (< 0.08). The
instrument has been proven to be a good instrument and passed
the psychometric standards.
Index Terms—Knowledge, Rasch model, structural equation
modeling, skill.
