Comparative Analysis of Reliability Estimates of Assessment Methods by Teachers in Secondary Schools in Port Harcourt Metropolis (Published)
The present study was on comparative analysis of reliability estimates of assessment methods by teachers in secondary schools in Port Harcourt Metropolis. Three objectives and research questions guided the study. Comparative research design was adopted in the study. The population of the study consisted of 3,340 SS2 students drawn across public schools in Port Harcourt metropolis. A sample of 100 students drawn across 10 schools in the area with the help of multi-stage sampling process was used in the study. The researcher developed two forms multiple-choice test as measuring instruments. The first was a 60 item “Formative Assessment Test” (FAT) while the second was a 50 item “Summative Assessment Test” (SAT). The FAT was administered on the respondents during the course of the instruction within the term while SAT was administered at the end of the third term as part of the promotional examinations. Test blueprint was adopted to ensure that the two instruments have content validity while factor analysis was used in determining the construct validity. Administrations of the instruments were done face to face in the class with the help of the classroom teachers. Data analysis method included KR20 , split-half and test retest methods of reliabilities. For the test-retest, the researchers repeated the process for both the formative (FAT) and summative test (SAT) after a period of two weeks interval. Result of the study showed that when KR20 was used, summative assessment had higher reliability that formative assessment (SAT-0.81>FAT-0.52). When split-Half was used, summative assessment also had higher reliability that formative assessment (SAT-0.87>FAT-0.58). However, when test retest was applied, formative assessment had higher reliability than summative assessment (FAT-0.78>SAT-0.55). Based on this, it was recommended among others that teachers and test developers should rely more of summative assessment in the course of establishing the cognitive abilities of students.

Performance Assessment of Secondary School Counsellors in Counselling: Anambra And Enugu States of Nigeria in Focus (Published)
The study sought to determine the performance assessment of counsellors in counselling as a school guidance service in Nigerian secondary schools. One research question and one hypothesis were formulated to guide the descriptive survey study. The population of the study was 47010 respondents out of which multistage sampling technique was used to select a sample of 739 respondents, being 45 supervisors and 675 SS II students. A 4 point researcher made 7 items questionnaire tagged Performance Assessment of School Counsellors in Counselling (PASCIC), with a reliability index of 0.73, Cronbach alpha was used to elicit responses after which 720 copies were duly filled and returned. Mean and t-test at 0.05 level of significance were used to test the research question and the hypothesis respectively. Findings reveal that Nigerian counsellors, in the face or all odds are proficient in counselling which would be traceable to cultures and traditions of counselling by elderly people in Nigeria to the younger ones.
