The law that, among other things, also establishes the figure of the professional pedagogist in Italy (law 205/2017, art. 1 594-601) has finally been approved by the Italian Parliament (20-27 December 2017): it provides for a qualification university. This has made up for a serious gap compared to the many more advanced countries in this regard. In this paper we summarize who the professional pedagogist is and what his professional profile is, what his professional practice techniques and procedures are and how he applies to his problems. Pedagogy is a social science, a science in the strict sense, and by its nature it is, at the same time, a social profession, whose origins refer to classical Greece and Latinity. The pedagogist is, appropriately, the top and top professional of the educational field. In this chapter we briefly examine some important examples of the rich and diversified "toolbox" that the pedagogist can use in his professional practice, in the context of a composite culture for a plurality of inputs of various disciplinary origins, concerning professional practice. Different social and psychological sciences make their contribution, understood and treated as "sciences of education /sciences de l’éducation".
