3 0. Introduction (background and Job Areas 1 ) The Leonardo_ECNL project was approved by the European Community with the aim of performing a feasibility study on a proposal for a Networking European Certification and outlining a possible educational model for young people seeking their first job opportunity, as well as already employed adults (Life Long Learning). Il progetto Leonardo_ECNL è stato approvato dalla Comunità Europea con l intento di realizzare lo studio di fattibilità di una proposta di certificazione europea del networking ed evidenziare un modello di formazione possibile per giovani in cerca di primo impiego e per adulti già occupati (Life Long Learning). As mutually agreed by project partners, the educational model to be designed will refer to professional areas (job areas) already defined by the European Community. The main issue thus consists in defining, in agreement with other countries participating in the project, professional profiles within a well-defined technological area, for which a syllabus for skills certification has been already established (refer to workpackage 6 for further details). The relevant technological area regards wired and wireless networks, as well as network operating system. Various educational profiles within this professional area, with varying degree of detail, have been considered. Arguments covered by this project are therefore internetworking, network administration and design of both LAN and WAN networks. The design of common educational pathways and the sharing of skills identification among different European countries will lay the basis for transversal educational systems; in this way, the various European educational systems, while having different origins and histories, will be able to establish common and homogeneous professional standards throughout Europe. This will account for the effective recognition of academic degrees and educational credits in all European countries. Il modello di formazione da progettare, concordato fra i diversi partner, farà riferimento ad aree professionali (job area) già definite dalla Comunità europea. Il lavoro consiste pertanto del definire e concordare fra i paesi partner del progetto declinazioni di profili professionali su un area tecnologica ben precisa e rispetto alla quale è già stato definito un syllabus di certificazione di competenze (vedasi riferimento workpackages 6). L area tecnologica di riferimento abbraccia le reti fisse e mobili ed i sistemi operativi di rete. Si è voluto pensare anche a diversi percorsi di studio nell area professionale strutturando il lavoro su diversi livelli di approfondimenti. Sono state pertanto anche affrontate le problematiche legate all internetworking ed alla comunicazione fra reti, alla amministrazione ed al progetto di reti LAN e di reti WAN. Progettare e concordare percorsi formativi comuni e definire competenze condivise fra diversi paesi europei, significa gettare le premesse per una trasversalità fra i sistemi di formazione, che pur avendo origine e storie diverse, tendono alla formazione di un livello di professionalità comune ed omogeneo in tutta Europa. Ciò significa anche rendere effettivo il riconoscimento dei titoli di studio conseguiti ed il riconoscimento dei crediti formativi. WP1_courseware.doc Pagina 3 di 49

13 6. Correlation between professional profile and ECNL certificate. The importance of correlating a professional profile with skill certifications arises from the fact that professional training constitutes the main way to obtain formal certification of acquired skills. The acquisition of additional, more advanced skills lays the basis for life-long learning, as repeatedly advocated by the European Community. The strict correlation between professional skills and certification objectives, shared by the different European countries, is an effective mean to make different European educational boards communicate with each other and define common minimum criteria in the technical training area. Il significato di mettere in correlazione il profilo professionale con la descrizione di una certificazione di competenze, sta nel fatto che la formazione professionale è il principale strumento che consente di acquisire l attestato formale della certificazione stessa. Conseguire elementi di professionalità nuovi e più avanzati è un modo di realizzare nel concreto quella ipotesi di formazione continua (Life Long Learning) ripetutamente propugnata dalla Comunità Europea. La stretta correlazione fra competenze professionali ed abilità da acquisire, con gli obiettivi della certificazione, condivisi fra i diversi paesi europei, è un modo efficace per mettere in comunicazione parti dei sistemi formativi dei diversi paesi europei e definire obiettivi minimi condivisi nell area della formazione tecnica.

25 7. An example of professional profile (with specific reference to Italian IFTS project criteria) The IFTS courses (IFTS: Istruzione e Formazione Tecnica Superiore) constitute in Italy a novel model for technical training, already experimented for a few years throughout Italy. According to such model, a professional profile, created and then declined, i.e. described by each school or Professional training Centre, according to the MIUR directives (MIUR: Ministero Istruzione Università Ricerca). The educational programme must be arranged by four students: a) School (usually a technical secondary school); b) Professional training centre c) University and/or Polytechnic d) Enterprise (or consortium) Moreover, the educational programme must be articulated in Capitalizable Units. Within the educational programme, each Capitalizable Unit constitutes a single entity, which is described by a list of competences and activity areas (AA), and corresponds to a credit unit that will be awarded to students that have passed suitable examinations established in advance by the programme designer. The subdivision of the educational programme in Capitalizable Units will allow to: promote the official recognition of acquired skills and competences, thus ensuring transparency to individuals and enterprises both on a national and European basis; let individuals capitalize on the competences acquired during their own professional and educational pathway, since all educational credits contribute in forming individuals overall competences; favour transparency and comparability of educational pathways; promote flexibility, modularity and personalization of individual educational pathways within an educational credits-based system. 8. Capitalizable Units system and credits: general characteristics. The Capitalizable units system can be schematised according to the following, strictly interrelated aspects: Structured in Units Capitalizable Certifiable Aggregated according to the specific educational pathway Centred on Activities Skills basic technical-professional transversal Referring to Primary requisites for job occupancy Activity areas and organization processes Individuals behaviour in the work context WP1_courseware.doc Pagina 25 di 49

26 Characterized by Flexibility Personalisation The overall structure of the educational programme is reported in the following figure. General Vocational training course Duration of the course: hrs Professional Competences Basik skills 20%hrs Cross skills 10% hrs Other s skills Other s skills ECNL certification Training 30% hrs Assessmen ts & exams Acquired skills and competences will be recorded in the Portfolio, which was specifically designed for the Leonardo project. 9. Example of professional profile (Italian case study) In this section, an example of professional profile will be reported, which is based on the job area of reference (Data Communication Engineering), but is also related to the ECNL certificate. In fact, this course was specifically conceived as a preparing course for the ECNL certificate. Therefore, each C.U. is associated with a specific level of the ENCL certificate (for details, please refer to the ECNL_Syllabus.doc document). Having in mind the Italian educational system, the educational programme comprises both the basic and transversal competences already defined for the Italian IFTS courses. Each country participating in the project could eliminate or modify, either totally or partially, basic and transversal competences. On the contrary, fulfilment of the Leonardo project objectives requires that professional competences are valid and recognized in all European countries. Description of competences related to the professional profile: As far as basic and transversal competences are concerned, minimal standards for the IFTS courses, defined on a national basis by the D.I. 31 st October 2000, n. 436, will be adopted. [Note: In the following table, the synopsis of the professional profile is reported.
