Law 56/2003, of 16 December, of Employment, establishes, in its article 3, that it corresponds to the Government, on a proposal of the current Ministry of Labour and Immigration, and prior report of this Ministry to the Sectoral Conference of Employment and Industrial Affairs, the elaboration and approval of the regulatory provisions in relation to, among others, occupational and continuing vocational training in the State field, as well as the development of such management.
Article 26.1 of Law 56/2003 of 16 December 2003, following the amendment by Royal Decree-Law 3/2011 of 18 February 2011 of urgent measures for the improvement of employability and reform of policies In the field of employment, it is concerned with the vocational training subsystem for employment, in which, since the entry into force of Royal Decree 395/2007 of 23 March, which regulates it, the arrangements for vocational training in the field of employment have been integrated labour-training and continuing training. This subsystem, according to the legal provisions laid down in the Organic Law of the European Communities, of Qualifications and Vocational Training, will be carried out in the framework of the National System of Qualifications and Vocational Training. of the National Employment System.
For its part, the Organic Law of June 19, the Organic Law of 19, understands the National System of Qualifications and Vocational Training as the set of instruments and actions necessary to promote and develop the integration of offers of vocational training and the assessment and accreditation of professional skills. The main instruments of this System are the National Catalogue of Professional Qualifications and the procedure for recognition, evaluation, accreditation and registration of the same. Article 8 of the Organic Law of 19 June provides that certificates of professional competence prove the professional qualifications of those who have obtained them and that they will be issued by the competent administration, with a view to official and valid throughout the national territory. In addition, Article 10.1 indicates that the General Administration of the State, in accordance with the provisions of Article 149.1.30. and 7. of the Constitution and after consulting the General Council of Vocational Training, shall determine the qualifications and certificates of professionalism, which shall constitute the offers of vocational training referred to in the National Catalogue of Professional Qualifications.
The National Catalogue of Professional Qualifications, according to Article 3.3 of Royal Decree 1128/2003 of 5 September, which regulates the National Catalogue of Professional Qualifications, in the wording given to the By the same token, Royal Decree 1416/2005 of 25 November provides the basis for drawing up the training offer leading to the acquisition of vocational training qualifications and certificates of professionalism and the modular training offer. the cumulative associated with a competition unit, as well as other training offers adapted to collectives with specific needs. In accordance with Article 8.5 of the same royal decree, the training offer of certificates of professionalism shall be in accordance with the minimum quality indicators and requirements which guarantee the fundamental aspects of a system. training, to be established by mutual agreement between the educational and labour administrations, after consultation of the General Council for Vocational Training.
Royal Decree 34/2008 of 18 January, governing certificates of professionalism, as amended by Royal Decree 1675/2010 of 10 December 2010, has updated, in line with the regulations mentioned above, the regulation of the certificates set out in the previous Royal Decree 1506/2003 of 28 November 2003 laying down the guidelines for certificates of professionalism, which have been repealed.
In that Royal Decree 34/2008, as amended by Royal Decree 1675/2010, the structure and content of the certificates of professionalism are defined, from the National Catalogue of the Professional Qualifications and the guidelines established by the European Union, and provides that the State Employment Public Service, with the collaboration of the National Focal Points, will develop and update the certificates of professionalism, which will be approved by real decree.
On the other hand, in the new wording of article 11.2 of the recast text of the Law of the Workers ' Statute, introduced by Royal Decree-Law 10/2011 of 26 August, of urgent measures for the promotion of employment Young people, the promotion of stability in employment and the maintenance of the programme of vocational retraining of people who wear out their unemployment protection, the new contract for training and apprenticeship is regulated in which it is establishes that the qualification or professional competence acquired through this new figure The contract shall be accredited through, inter alia, the certificate of professionalism or the cumulative partial certification.
In this regulatory framework it is appropriate for the Government to establish three certificates of professionalism of the professional family Manufacturing Mechanics of the professional areas of Metallic Constructions and Mechanical Operations incorporate into the National Directory of certificates of professionalism by levels of professional qualification, in the light of the professional competence required by the production activities, as set out in Article 4.4 and Annex II of the Royal Decree 1128/2003, cited above.
With the entry into force of this royal decree, the new certificate of professionalism "Soldering oxygenas and welding MIG/MAG" which in it is established, replaces the certificate of professionalism of the occupation of Soldador de light metal structures, set out in Royal Decree 82/1997 of 24 January, which is therefore repealed.
With the entry into force of this royal decree, the new certificate of professionalism "Welding with coated electrode and TIG" which in it is established, replaces the certificates of professionalism of the occupation Welder of heavy metal structures, established in Royal Decree 87/1997, of January 24, and the certificate of professionalism of the occupation of Solder of pipes and vessels of high pressure, established in Royal Decree 88/1997, of 24 of January, which, as a result, are repealed.
