What determines the legal standards for paralegals?

The legal standards for paralegals are primarily determined by the laws and regulations established by individual states, professional organizations, and the legal profession itself rather than a single entity like the American Bar Association, the Supreme Court, or Congress. The American Bar Association does provide guidelines and model rules regarding the role of paralegals, but it does not have the authority to set legal standards that are binding across all jurisdictions.

While the Supreme Court of a licensing state may issue rulings that impact legal practice, it does not directly create standards for paralegals. Similarly, the United States Congress creates federal laws and does not regulate state-level professions like paralegals. Consequently, without a single governing body dictating comprehensive standards, the correct answer reflects that there isn't a definitive choice among the given options that accurately represents how legal standards for paralegals are established.
