ITEM 4.01. CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT



Technology Funding Venture Partners IV, An Aggressive Growth Fund,
L.P., (the "Partnership") received notification from Grant Thornton LLP
("Grant Thornton") on June 29, 2005, stating that Grant Thornton will
terminate the client-auditor relationship with the Partnership
effective upon the filing of the Partnership's Form 10-Q for the
quarter ended June 30, 2005. Based on a recommendation by the
Partnership's Independent General Partners, management is currently in
the process of evaluating a replacement independent audit firm.

In connection with the audits of the two fiscal years ended December
31, 2003 and 2004, and the subsequent interim period through the date
of this Form 8-K, there were no disagreements with Grant Thornton on
any matter of accounting principles or practices, financial statement
disclosure, or auditing scope or procedure, which disagreements if not
resolved to its satisfaction would have caused Grant Thornton to make
reference in its report on the Partnership's financial statements as of
and for the fiscal years ended December 31, 2003 and 2004.

The audit reports of Grant Thornton on the financial statements of the
Partnership as of and for the years ended December 31, 2003 and 2004,
did not contain any adverse opinion or disclaimer of opinion, nor were
they qualified or modified as to uncertainty, audit scope, or
accounting principles.

During the fiscal years ended December 31, 2003 and 2004, and through
the date of this Form 8-K, there have been no reportable events (as
defined in Regulation S-K Item 304(a)(1)(v)).

The Partnership provided Grant Thornton a copy of this Form 8-K prior
to its filing with the Securities and Exchange Commission.  A letter
from Grant Thornton stating whether it is in agreement with the
statements contained herein is attached as Exhibit 16.1.



                                    SIGNATURE


                  Pursuant to the requirements of the Securities
Exchange Act of 1934, the registrant has duly caused this report to be
signed on its behalf by the undersigned thereunto duly authorized.
