פירוש על קידושין 97:11

For a man to be a “Torah reader” all he has to do is read three verses in the synagogue, the minimum number for an aliyah. R. Judah says he must also be able to translate into Aramaic.

The Talmud clarifies that to translate does not mean to make up one’s own translation. It means to recite the official translation sanctioned by the sages.
