Dans le domaine des centres d’appels, l’affectation d’agents au service à la clientèle efficaces et satisfaits représente une activité cruciale pour toute direction dédiée aux ressources humaines de ces unités d’affaires. Or, pour parvenir à prendre de bonnes décisions d’embauche et de rejet, des instruments de mesure et d’évaluation des compétences sont souvent mis à contribution. À cet effet, les tests de jugement situationnel (TJS) sont de plus en plus utilisés pour la sélection du personnel. L’objet de cette thèse est donc de vérifier l’efficacité relative des différentes méthodes d’élaboration des grilles de correction des TJS. En effet, jusqu’à présent, trois méthodes ont été privilégiées par les concepteurs de tests (Weekley, Ployhart, & Holtz, 2006) : (1) l’approche rationnelle ou théorique (2) l’approche empirique et (3) le recours à des experts. La possibilité qu’une combinaison de ces différentes approches puisse conduire à de meilleurs résultats est également explorée. Pour y parvenir, le résultat total obtenu à un TJS a été mis en lien avec une évaluation du rendement global effectuée par un supérieur immédiat en y appliquant huit grilles de correction différentes. Au total, un échantillon de 312 employés œuvrant dans des emplois de téléopérateurs au sein d’une grande institution financière québécoise ont participé à cette recherche. Dans l’ensemble, les résultats indiquent qu’une approche empirique permet généralement d’obtenir de meilleures statistiques descriptives en termes de distribution et de dispersion des scores pour un processus de sélection. Cependant, des analyses corrélationnelles indiquent qu’une approche multiple ou méthode hybride, basée sur une intégration des informations fournies par différentes sources d’informations (empirique, théorique et basé sur les experts) pour l’élaboration d’une grille de correction d’un TJS, permet de mieux prédire le rendement des employés (r=0,247**) comparativement à l’utilisation de la théorie pour définir les attentes (r=0,162**), le recours à des experts de contenu œuvrant dans le domaine de pratique (r=0,164**) ou l’utilisation d’une approche empirique (r=0,154*). Mots clés : Test de jugement situationnel, grilles de correction, validité critériée, centre d’appels.

The provision of children's content should be a key constituent of the public service brand, but has often been viewed as a programme category at risk. Certainly in many countries children's television has moved from the 'scarcity' associated with terrestrial provision, to the 'plenty' of digital (see Ellis 2000). However in spite of a range of dedicated public service children's channels in Europe (CBeebies, Kika, Z@ppelin), domestically produced children's television in Europe is notoriously under-resourced if not marginalised. There is a pronounced reliance on imports (particularly on commercial television) notwithstanding the launch by US-owned multinationals (Disney, Nickelodeon, Cartoon Network) of localised versions of their children's television channels in many European countries. Within the broader context of global developments in children's media, this paper starts by outlining the recent and rapid crisis in British children's television and the factors that caused it. This was a crisis, which caught broadcasters and producers by surprise in the middle of 2006, but reflects many of the challenges faced by the children's television sector in other countries. It clearly demonstrated how a combination of the lack of regulatory protection, a change in commercial priorities among broadcasters, advertising restrictions, budgetary pressures and the competitive environment at home and abroad all combined to reinforce the trend towards a contraction of domestic production. The crisis also served to underline the dominance of the BBC - both as a representative of public service principles, and as the dominant producer and commissioner in the market. With the reasons underpinning the crisis explained, the paper will then analyse how the children's television community responded to the crisis and with what effect. Based on interviews, contemporary accounts and documentary evidence the paper will chart the converging and diverging views of broadcasters, producers, regulatory authority Ofcom, and a range of advocacy groups which represent children's interests and the industry. What arguments were elaborated in favour of protecting children's television as an integral part of the public service media brand? Can lessons be learned about how best to ensure the origination of children's media within a public service environment? Can developments in the UK be used to provide insight into how children's media might develop further?
