Selection and selection procedures play a key role in the ability of organisations to compete successfully in the complex global and local environment. South Africa is experiencing a serious artisinal and technical skill shortage. Given the unemployment issues and the quest for people to fill the skill shortage gap it is important for organizations to find possible solutions to ensure that they stay competitive and effective in the labour market. Research suggests that at least 12 500 artisans need to be produced each year from 2006 to 2010 to meet the demand for skilled workers. To address above mentioned challenge organizations have to develop strategies to assist them to select individuals with the best chance to succeed in training. Unfortunately, the solution is not simple as organisations have a multitude of influences and pressures which affect their decisions regarding selection procedures. Selection of individuals is becoming an increasingly complex science as organisations have to select a capable and representative workforce. They must thus select candidates that are most likely to benefit from what is offered educationally, meet the requirements stipulated in South Africa's Labour legislation, and will perform most successfully in the specific trade. Bad practice can lead to costly litigation. The objectives of this mini-dissertation were to assess the empirical validity of the Technical Test Battery (TTB), as ability test and the Learning Potential Computerised Adaptive Test (LPCAT) as learning potential test as predictors of academic success of first year apprentice electrician students at a South African technical college serving a mining community. The study explored the current local employment issues that affect selection for training in the technical fields. The difference between the measurement of cognitive ability and learning potential were examined and the nature of the constructs of cognitive ability and that of learning potential were discussed. In the empirical study one of the objectives was to determine whether there was a relationship between the TTB and the LPCAT as two different predictors of the academic success of first yar apprentice electrician students. The difference in the empirical (predictive) validity of the two psychometric selection instruments, if only one of the tests as opposed to if both were used in combination, were examined. Another objective was to determine if there were any differences regarding the scores on the TTB and LPCAT of students from the designated group as opposed to that of students from non-designated groups. Finally this study explored whether the TTB and LPCAT were valid predictors to be used as selection instruments for apprentice electrician students in the South African context The research method consisted of a literature review and an empirical study. The empirical validity of the two predictor tests was validated in terms of the accuracy with which the selection instruments predicted the students' future performance. This research can be categorized as descriptive quantitative research. The TTB and LPCAT scores of a sample of 89 selected apprentice electricians were compared with the number of attempts they used to pass a phase test. Data was analysed by means of descriptive statistics. Pearsons Product Moment Correlation Coefficient, t-tests, ANOVAs as well as discriminant analysis were also used to reach the research objective. Statistically significant relationships were found between the predictor and criterion variables. The results confirm that the TTB and LPCAT are indeed empirical valid tests that can be used in the selection of apprentice electricians. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2008.

Personalen är i många fall den viktigaste resursen för olika företag. Likaså är den rekryteringsprocess som leder fram till anställning av rätt personal. Rekryteringsprocesser består av olika moment där företag kompletterar sina arbetsprofilsbedömningar medtestverktyg för att hitta de bäst lämpade kandidaterna för de vakanta tjänsterna. Två av dessa verktyg är de personlighet och begåvningstester som sökande kandidater genomför, där resultatet påverkar möjligheten till anställning. Användningen och påverkan av användningen berör företag på olika sätt, men det finns flera gemensamma nämnare vad gäller testernas roll i rekryteringen. Vi kommer i uppsatsen att ta reda på hur testerna som verktyg påverkar rekryteringen i företag genom att utreda både de positiva och negativa effekterna. Vi kommer även undersöka hur tilliten till testernas resultat och till testerna generellt ser ut. Tillvägagångssättet för att ta reda på detta kommer att ske genom intervjuer. 15 respondenter som är högst insatta i ämnet och på något sätt är eller har varit aktiva användare av testerna som verktyg, ligger till grunden för vårt underlag till empirin. Testerna som verktyg bidrar till en av oss upplevd motsägelsefullhet hos användarna. Det finns vitt skilda meningar kring validiteten i testresultaten. Det finns en sida som är positivt inställd till testerna och belyser fördelarna med användningen. Det finns en annan sida som pekar på att testerna som verktyg istället ger motsatt effekt och kan skada både rekryteringen och kandidaten som genomför testet. / In many cases, the staff is the most important resource for different companies, and the recruitment process should lead to the hiring of the most suitable staff. The recruitment process consists of different events where the company expands its job profiles with different types of test tools to find the best candidates. Two of these tools are the personality and ability tests that many applicants need to do when applying for a new job. Companies have different strategies and execution regarding the tests but there are several common denominators regarding the test rolls in recruitment. In the thesis, we will investigate test tools used in companies' recruitment processes, by calling out both the positive and negative effects. We will also examine how much trust the companies have in the results of the tests and how the tests generally contribute to recruitment. The research approach to finding out will be through interviews. All 15respondents are highly proficient in the subject and they are or have in some way been active users of the tests. The tests as tool support to a contradiction among the users. There are widely differing opinions on the validity of the test results. There is one group that is positively tuned to the tests and sees several benefits with its use. There is another group that points to the test as a tool instead gives the opposite effect and can damage both the recruitment and the person doing the test.

The present study addressed the lack of cognitive assessment instruments in the educational settings of adolescent and young adult students who are incarcerated in juvenile correctional institutions. The purpose of the study was to develop and validate a verbal problem solving questionnaire. The design of the Everyday Problem Questionnaire (EPQ) was based on a model and testing method for assessing cognitive development throughout the life-span. The study was conducted in two phases. In the first phase, the Everyday Problem Questionnaire was developed from descriptions of everyday life problems that were submitted in writing by 47 randomly-chosen males, aged 18 through 24 years, who were incarcerated in a high security state youth correctional institution. A second group of 25 randomly-chosen students from the same institution, rated the life problems on four criteria: (a) typicality, (b) personal experience, (c) interest level and, (d) level of difficulty. Nine problems were included in the final Everyday Problem Questionnaire. In the second phase, the new Everyday Problem Questionnaire was administered to a group of 54 randomly-chosen late adolescent and young adult males who were incarcerated. Four commonly used measures of cognitive ability and achievement were also administered, the Kaufman Adolescent and Adult Intelligence Test, the Test of Non-verbal Intelligence-Two, Second Edition, and the Woodcock-Johnson Tests of Achievement-Revised for reading and mathematics. The Everyday Problem Questionnaire responses were scored by three educators from the institution, who received training on an experimental scoring system that was a model of problem solving that included five steps. The other measurements were scored by a professional school psychologist. In the analyses of the first phase ratings indicated that the EPQ was shown to consist of life problems representative of adolescents and young adult males who have been incarcerated. Subsequent validation of the EPQ scoring system was not successful in the second phase of the study due to inconsistent inter-rater reliability. Consequently, the instrument could not be compared with results on other tests of cognition and achievement. Specific suggestions are made for designing a more reliable and stable scoring system. Issues regarding research and institutional access to students in a high-security youth corrections institutional setting are also discussed.

The aim of this research was (1) to provide empirical data of learning potential and English language proficiency for work performance; (2) to establish whether race and gender influence work performance; (3) to evaluate practical utility and to propose recommendations for selection purposes. The Learning Potential Computerised Adaptive Test and the English Literacy Skills Assessment were used as measuring instruments to measure learning potential and English language proficiency respectively. Work performance data were obtained from the normal performance data system of the company where the research was conducted. ANOVA results showed differences between race and gender groupings. A regression analysis confirmed the predictive validity of learning potential and English language proficiency on work performance. The Spearman rho correlation coefficient (p < 0.05) showed a significant positive correlation between the investigated variables / Industrial & Organisational Psychology / M. A.
