The objective of this research was to investigate the influence of weighted and unweighted rating scales, and internal and external assessors on information function of performance test. The study was conducted on the even semester of 2004 at seven vocational schools in West Sumatera, involving 864 students and 46 performances. The sample was drawn by using simple random sampling technique, and placement was done by means of random matrix method. Factorial 2x2 design was adopted in this study. Data were collected through a performance test, and analyzed by using Rasch and two-way analysis of variance. The results of the research are: (1) the information function of the weighted rating scale test was more effective than the unweighted rating scale test, (2) the information function of the students test assessed by external assessors was higher than that assessed by internal assessors, (3) The interaction factor between types of performance test (weighted and unweighted) and assessor groups (internal and external) affected the information function of test, (4) the information function of unweighted rating scale used by internal assessors was higher than that used by external assessors, (5) the information function of unweighted rating scale used by internal assessors was higher than the information function of weighted rating scale used by internal assessors, (6) the information function of weighted rating scale used by external assessors was higher than that of weighted rating scale used by internal assessors, (7) the information function of weighted rating scale used by external assessors was higher than that of unweighted rating scale used by internal assessors.
