The proportion of individuals with little training varies greatly among European countries. Throughout Europe, nonparticipation in the labor market and unemployment seem relatively synonymous. Three degrees of labor market openness with regard to individuals with low levels of training are apparent throughout Europe: (1) in Portugal, skill acquisition occurs through channels other than a formalized training and certification system and the labor market remains relatively open to low-skilled people; (2) in Sweden, France, and the Netherlands, the labor market is becoming increasingly closed to low-skilled individuals; and (3) in the United Kingdom, labor force nonparticipation and unemployment tend to be higher among low-skilled individuals but their ability to enter the labor market has remained relatively stable. Young people (ages 25-29) with little training are especially vulnerable to nonparticipation in the labor market. The argument that women without training tend to remain at home and invest themselves in extraprofessional activities has not been totally verified. When everyone exiting a country's educational system obtains a certificate that allows labor market access, the lack of a certificate ends up being even more stigmatizing for those unable to attain even this minimum standard. One path worth exploring throughout Europe is that of accompanying low-skilled individuals who experience difficulty during the process of labor market entry to allow them to acquire a certain experience and strengthen their training during the process.
