From the Code of Canon Law:
Can. 230. sec. 1. Lay men Viri laici] who possess the age and qualifications established by decree of the conference of bishops can be admitted on a stable basis through the prescribed liturgical rite to the ministries of lector and acolyte. Nevertheless, the conferral of these ministries does not grant them the right to obtain support or remuneration from the Church.
sec. 2. Lay persons Laici] can fulfill the function of lector in liturgical actions by temporary designation. All lay persons Omnes laici] can also perform the functions of commentator or cantor, or other functions, according to the norm of law.
sec. 3. When the need of the Church warrants it and ministers are lacking, lay persons laici], even if they are not lectors or acolytes, can also supply certain of their duties, namely, to exercise the ministry of the word, to preside over liturgical prayers, to confer baptism, and to distribute Holy Communion, according to the precepts of the law.
Can. 910, sec. 2. The extraordinary minister of holy communion is an acolyte or another member of the Christian faithful designated according to the norm of can. 230, sec. 3.
So women, as lay persons, can serve in the above capacities according to the norm or precepts of the law, but cannot become a duly instituted lector or acolyte.
