AB - This document provides a comprehensive summary of the state-of-the-art, challenges, and prospects in the experimental and theoretical study of the strong coupling α<sub>s</sub>. The current status of the seven methods presently used to determine α<sub>s</sub> based on: (i) lattice QCD, (ii) hadronic τ decays, (iii) deep-inelastic scattering and parton distribution functions fits, (iv) electroweak boson decays, hadronic final-states in (v) e+e-, (vi) e-p, and (vii) p-p collisions, and (viii) quarkonia decays and masses, are reviewed. Novel α<sub>s</sub> determinations are discussed, as well as the averaging method used to obtain the PDG world-average value at the reference Z boson mass scale, α<sub>s</sub>(m<sup>2</sup><sub>Z</sub>). Each of the extraction methods proposed provides a 'wish list' of experimental and theoretical developments required in order to achieve an ideal permille precision on α<sub>s</sub>(m<sup>2</sup><sub>Z</sub>) within the next 10 years.
