This study aimed at examining the quality of an English summative test of grade VII in a public school located in Kupang. Particularly, this study examined content validity, reliability, and conducted item analysis including item validity, item difficulty, item discrimination, and distracter effectiveness. This study was descriptive evaluative research with documentation to collect data. The data was analyzed quantitatively except for content validity, which was done qualitatively. Content validity was analyzed by matching the test items with materials stated in the curriculum. The findings revealed that the English summative test had a high content validity. The reliability was estimated by applying the Kuder-Richardson’s formula (K-R20). The result showed that the test was reliable and very good for a classroom test. The item analysis was conducted by using ITEMAN 3.0. and it revealed that the the test was mostly constructed by easy items, most of the items could discriminate the students, most distracters were able to perform well, and the most of items were valid.

While almost half of the teachers’ activities are assessing their students, they are not well-prepared with assessment literacy training. Hence, they are unable to produce good tests to measure students’ level of knowledge and skills. This study is aimed at analyzing item difficulty and item discrimination of a test made by an English teacher at a junior high school in Kupang. It was descriptive qualitative research and the instruments of the research were test items, answer keys, and students’ answer sheets. For the difficulty index, it was revealed that more than half of the test items were easy, while only 2% of the test items were difficult. In terms of the discrimination index, it was found that only 10% of the test items were excellent and most of the test items (46%) were poor. These findings indicated that the English test had a poor item difficulty index and low item discrimination index. Hence, it did not fulfill the criteria of a good test and could not measure students’ true ability. It is highly recommended for the teachers to improve the test items and for the government to provide assessment training for the teachers so that they can produce good tests.

Descriptive Method

This research was conducted by using a descriptive method with a quantitative approach. The quantitative approach was chosen to be tested theories by examining and measuring variables in the form of relationships, differences, influences, contributions, and the others. The research was carried out by describing the students acquisition data on the new student admission (PPDB) using zoning system based on the academic year 2019-2020 and the student acquisition data on the academic year PPDB 2018-2019 as a comparison. Based on the results of the study, the new students of PPDB using zoning system was considered lower in terms of economic and educational background of parents. There were more parents with less education (elementary & junior high school) in the zoning system than in the rayon system, whereas parents with higher education in the zoning system were fewer than the rayon system.  Likewise, in terms of income, there were more people with the low income in the zoning system than in the rayon system, and those having high income were fewer than in the rayon system. The study showed that the intelligence and the result of National Examination Score (NUN) in the zoning system is lower than in the rayon system. The intelligent level of the students in the zoning system is mostly dominated by the scores under 90-109, while in the rayon system were dominated by the scores above 90-109.  The National Examination Scores (NUN) in the zoning system were evenly distributed from a range of scores 0 to 30, while in the rayon system the scores were dominated by a range of scores 28-30, with the lowest score 24.

This study was motivated by the low score of the students‘ Indonesian language in national examination that were certainly correlated with the Indonesian language teachers‘ competences. The Indonesian language techers‘ competences can be observed in doing the Indonesian language proficiency test. This study was aimed to determine the Indonesian language teachers‘ capabilities indoing UKBI and to describe about it. The data obtained describe that the Indonesian language teachers of Senior High School (SMA) have the highest scores, then the Indonesian language teachers of Junior High School (SMP), and the last ones were the teachers of elementary school (SD). Moreover, among the Indonesian language techers‘ capabilities of SMA, SMP, and SD in doing UKBI have not shown the significant differences.AbstrakPenelitian ini dilatarbelakangi oleh rendahnya nilai Ujian Nasional (UN) bahasa Indonesia siswa yang tentunya berkorelasi dengan kompetensi guru bahasa Indonesianya. Kompetensi guru bahasa Indonesia dapat terlihat dari Uji Kemahiran Berbahasa Indonesia (UKBI). Penelitian ini bertujuan untuk mengetahui kemampuan guru bahasa dan sastra Indonesia di Pekanbaru dalam menyelesaikan soal UKBI dan untuk mendeskripsikan kemampuan guru dalam menyelesaikan soal UKBI. Dari penganalisisan data diperoleh temuan bahwa nilai rerata UKBI guru SMA memperoleh skor paling tinggi, nilai rerata UKBI guru SMP memperoleh skor sedang, sedangkan nilai rerata UKBI guru SD memperoleh skor paling rendah. Akan tetapi, kemampuan guru bahasa dan sastra Indonesia dari ketiga tingkatan sekolah tersebut (SMA, SMP, SD) dalam menyelesaikan soal UKBI tidak menunjukkan perbedaan yang berarti (tidak signifikan) pada taraf kepercayaan 5 %, hal ini terlihat dari nilai Fhitung lebih kecil dari Ftabel (Fhitung = 0,11 < Ftabel = 4,35)

The goal of the research is to gain insights into the characteristics of the items in the mathematics national examination, the attributes on which the items were formulated and the result of a conceptual error diagnosis of the mathematics materials based on the result of the junior high school mathematics national examination. This is quantitative descriptive research. The data were collected from 3,079 grade-nine students of junior high schools who took the National Examination in the academic year of 2015/2016. The sample was established randomly based on the package code of the examination which is P0C5520 with 574 students as the examinees. Documentation method was applied in collecting the data. The result of the research shows that – upon the implementation of the classical test theory – there are 16 items in ‘difficult’ category, 24 in ‘intermediate’ category, and no items in ‘easy’ category. Furthermore, upon the implementation of the item response theory, the result shows that 28 items are in ‘good’ category and 12 items are in ‘poor’ category. In addition, there are 50 attributes on which the Junior High School Mathematics National Examination test (package P0C520) is formulated. Four attributes are content attributes and the rest (46) are process skill attributes. The result of the diagnosis shows that there are 11 types of errors made by the students when trying to complete the content items. Most of the errors are conceptual errors related to the geometric materials especially in the sub-materials of polyhedron, triangles, and quadrangles.
