Genuine prophets are chosen by God, no qualifications are specified.
Numbers 12:6 And he said, Hear now my words: If there be a prophet among you, I the LORD will make myself known unto him in a vision, and will speak unto him in a dream.
Care had to be taken with respect to prophets.
Deuteronomy 13:1-5 If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder, 2 And the sign or the wonder come to pass, whereof he spake unto thee, saying, Let us go after other gods, which thou hast not known, and let us serve them; 3 Thou shalt not hearken unto the words of that prophet, or that dreamer of dreams: for the LORD your God proveth you, to know whether ye love the LORD your God with all your heart and with all your soul. 4 Ye shall walk after the LORD your God, and fear him, and keep his commandments, and obey his voice, and ye shall serve him, and cleave unto him. 5 And that prophet, or that dreamer of dreams, shall be put to death; because he hath spoken to turn you away from the LORD your God, which brought you out of the land of Egypt, and redeemed you out of the house of bondage, to thrust thee out of the way which the LORD thy God commanded thee to walk in. So shalt thou put the evil away from the midst of thee.
Deuteronomy 18:20-22 But the prophet, which shall presume to speak a word in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die. 21 And if thou say in thine heart, How shall we know the word which the LORD hath not spoken? 22 When a prophet speaketh in the name of the LORD, if the thing follow not, nor come to pass, that is the thing which the LORD hath not spoken, but the prophet hath spoken it presumptuously: thou shalt not be afraid of him.
There were many false prophets in Israel.
Jeremiah 23:14-16 I have seen also in the prophets of Jerusalem an horrible thing: they commit adultery, and walk in lies: they strengthen also the hands of evildoers, that none doth return from his wickedness: they are all of them unto me as Sodom, and the inhabitants thereof as Gomorrah. 15 Therefore thus saith the LORD of hosts concerning the prophets; Behold, I will feed them with wormwood, and make them drink the water of gall: for from the prophets of Jerusalem is profaneness gone forth into all the land. 16 Thus saith the LORD of hosts, Hearken not unto the words of the prophets that prophesy unto you: they make you vain: they speak a vision of their own heart, and not out of the mouth of the LORD.
Jeremiah 23:21 I have not sent these prophets, yet they ran: I have not spoken to them, yet they prophesied.
Jeremiah 23:25-26 I have heard what the prophets said, that prophesy lies in my name, saying, I have dreamed, I have dreamed. 26 How long shall this be in the heart of the prophets that prophesy lies? yea, they are prophets of the deceit of their own heart;
There were no genuine prophets from 400BC until the coming of Jesus Christ.
Amos 8:11 Behold, the days come, saith the Lord GOD, that I will send a famine in the land, not a famine of bread, nor a thirst for water, but of hearing the words of the LORD:
God promised a prophet like unto Moses:
Deuteronomy 18:18-19 I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him. 19 And it shall come to pass, that whosoever will not hearken unto my words which he shall speak in my name, I will require it of him.
That prophet was Jesus Christ.
Acts 3:22-23 For Moses truly said unto the fathers, A prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear in all things whatsoever he shall say unto you. 23 And it shall come to pass, that every soul, which will not hear that prophet, shall be destroyed from among the people.
Hebrews 1:1 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, 2 Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;
Jesus’ last prophecy is contained in the book of Revelation.
Revelation 1:1 The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass; and he sent and signified it by his angel unto his servant John:
Since that time there have been no genuine prophets. Prophets are no longer necessary. The Bible is complete; the gospel is complete; the doctrines are complete. All that we need to know for salvation is written down and available in the Bible.
All prophets since the end of the first century have been false prophets.
Matthew 24:24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
There are no genuine prophets today.
I hope you find this helpful.
