**Item 1.** **Distribution and Pool Performance Information.**<br>

On September 25, 2025, SLM Student Loan Trust 2013-6 (the "Trust") made its regular monthly distribution of funds to holders of its Student Loan-Backed Notes. Navient Solutions, LLC (formerly, Navient Solutions, Inc.), as the administrator, distributed the Monthly Distribution Report for the Trust for the period identified on the cover of this Form 10-D to the Indenture Trustee, on behalf of the Trust's noteholders of record. This Monthly Distribution Report is attached to this Report as Exhibit 99.1.

| **Item 2.** | **Legal Proceedings.** |

---

The following is disclosure received from Navient Solutions, LLC (formerly, Navient Solutions, Inc.) ("Navient Solutions"), the servicer for this transaction.

Navient Corporation ("Navient") has been named as defendant in a number of putative class action and other cases alleging violations of various state and federal consumer protection laws including the Telephone Consumer Protection Act, the Consumer Financial Protection Act of 2010 (CFPA), the Fair Credit Reporting Act (FCRA), the Fair Debt Collection Practices Act (FDCPA), in adversarial proceedings under the United States Bankruptcy Code, and various state consumer protection laws. At this point in time, Navient is unable to anticipate the timing of a resolution or the impact that these legal proceedings may have on its consolidated financial position, liquidity, results of operation or cash flows. As a result, it is not possible at this time to estimate a range of potential exposure, if any, for amounts that may be payable in connection with these matters and loss contingency accruals have not been established. It is possible that an adverse ruling or rulings may have a material adverse impact on Navient, Navient Solutions and/or their affiliates or on the financial ability of the depositor, the servicer or a seller to fulfill an obligation to purchase or repurchase trust student loans in connection with a breach of representation, warranty or covenant.

The following is disclosure received from Deutsche Bank National Trust Company and Deutsche Bank Trust Company Americas. Deutsche Bank National Trust Company ("DBNTC") and Deutsche Bank Trust Company Americas ("DBTCA") have been sued by investors in civil litigation concerning their role as trustees for certain residential ("RMBS") trusts.

On November 7, 2014, the National Credit Union Administration Board ("NCUA"), as an investor in 121 RMBS trusts, filed a complaint in the U.S. District Court for the Southern District of New York against DBNTC as trustee of those trusts, alleging violations of the U.S. Trust Indenture Act of 1939 ("TIA") and the New York Streit Act ("Streit Act") for DBNTC's alleged failure to perform certain purported statutory and contractual duties. On March 5, 2015, NCUA amended its complaint to assert claims as an investor in 97 of the 121 RMBS trusts that were the subject of its first complaint. The amended complaint alleged violations of the TIA and Streit Act, as well as breach of contract, breach of fiduciary duty, breach of the covenant of good faith, negligence, gross negligence and negligent misrepresentation. NCUA's complaint alleged that the trusts at issue suffered total realized collateral losses of U.S. $17.2 billion, but the complaint did not include a demand for money damages in a sum certain. On May 1, 2015, DBNTC filed a motion to dismiss the amended complaint. On July 31, 2018, the court issued an order that, among other things, denied DBNTC's motion to dismiss without prejudice to its renewal. On August 31, 2018, NCUA filed a letter informing the court that it intended to: (i) drop all of its claims as to 60 of the 97 trusts at issue; (ii) drop its claims as to certain, but not all, certificates for 3 additional trusts; and (iii) move for leave to file an amended complaint bringing claims as to the remaining 37 trusts at issue. On October 5, 2018, NCUA filed a motion for leave to file a second amended complaint that asserted claims as to only 37 of the 97 trusts that were originally at issue, and added new claims for a declaratory judgment and breach of contract arising out of the payment from trust funds of DBNTC's legal fees and expenses in NCUA's action and in other actions brought by investors against DBNTC for alleged breaches of its duties as an RMBS trustee. On November 5, 2018, DBNTC filed a motion to stay NCUA's new claims relating to payment from trust funds of DBNTC's legal fees and expenses and all related discovery. On October 15, 2019, the court: (i) granted in part NCUA's motion for leave to file a second amended complaint; and (ii) granted DBNTC's motion to stay NCUA's new claims relating to payment from trust funds of DBNTC's legal fees and expenses and all related discovery. The court permitted NCUA to file a second amended complaint asserting claims for: (i) breach of contract arising out of DBNTC's alleged failure to perform certain purported statutory and contractual duties; and (ii) declaratory judgment and breach of contract arising out of the payment from trust funds of DBNTC's legal fees and expenses. The court denied NCUA's request to assert additional claims for: (i) negligence and gross negligence; and (ii) breach of fiduciary duty. On October 21, 2019, NCUA filed a second amended complaint. On November 15, 2019, DBNTC filed an answer to the second amended complaint. On June 11, 2021, NCUA filed a third amended complaint, the substance of which was unchanged from the second amended complaint. On July 1, 2021, DBNTC filed an answer to the third amended complaint. On October 5, 2021, NCUA filed a fourth amended complaint, the substance of which was unchanged from the third amended complaint. On October 25, 2021, DBNTC filed an answer to the fourth amended complaint. On February 4, 2022, the parties filed a stipulation in which NCUA agreed to voluntarily dismiss with prejudice all claims as to 19 trusts. On February 28, 2022, both parties filed motions for partial summary judgment, which have been fully briefed. On August 11, 2025, the court granted in part and denied in part both motions. Discovery is ongoing.
