amendments to Form N-1A.  Each Fund's Registration Statement is as follows:

         For the staff's convenience, its comments are restated below, followed
by the Funds' responses.

Prospectuses (All Funds):

Excessive Trading

Comment 1.  In the last paragraph of the section on "Excessive Trading," please
clarify that any rejection or cancellation of a purchase or exchange order will
occur within one day.

The current disclosure is as follows: "The fund may reject a purchase or
exchange order before its acceptance or cancel any purchase or exchange order
prior to issuance of shares, which occurs within three days after receipt
of an order in good standing."

Response:  In accordance with subsequent discussions with the staff of the
Commission, the Funds will change the disclosure as follows:  "The fund may
reject a purchase or exchange order before its acceptance or an order prior
to issuance of shares."  The Funds acknowledge that the issue regarding the
necessary length of time required for a Fund to determine whether or not to
reject or cancel a purchase or exchange order may be revisited by the staff
of the Commission.

Statements of Additional Information (Pioneer Oak Ridge Large Cap Growth Fund,
Pioneer Oak Ridge Small Cap Growth Fund, Pioneer Select Equity Fund):

Investment Restrictions

Comment 2.  Please describe the investment restriction with respect to each
Fund's limitations on pledging, mortgaging or hypothecating assets in
connection with the Fund's limitation on borrowings.

Response:  The following italicized sentence will follow the Funds' stated
investment restriction on borrowing: "In the opinion of the SEC, the fund's
limitation on borrowing includes any pledge, mortgage or hypothecation of
its assets."

Statements of Additional Information (Pioneer Oak Ridge Large Cap Growth Fund
and Pioneer Oak Ridge Small Cap Growth Fund):

Investment Adviser

Comment 3.  Please add disclosure in the section on the subadvisory agreement
regarding any potential termination fee with respect to the subadvisory
agreement between Pioneer and Oak Ridge, as well as other information that
may be pertinent to shareholders regarding the terms of the termination fee.



Securities and Exchange Commission

Response:  Accepted.  The following disclosure will be added:

"Certain Agreements between Pioneer and Oak Ridge.  In connection with the
reorganization of (i) Oak Ridge Small Cap Equity Fund into Pioneer Oak Ridge
Small Cap Growth Fund and (ii) Oak Ridge Large Cap Equity Fund into Pioneer Oak
Ridge Large Cap Growth Fund, Pioneer and Oak Ridge entered into an agreement
dated as of September 22, 2003 (the "Transfer Agreement").  The Transfer
Agreement provides, among other things, that (i) Oak Ridge shall enter into and
perform its obligations under a Subadvisory Agreement to serve as subadviser of
the relevant fund, (ii) Pioneer shall pay Oak Ridge a fee, if within five years
of the closing of the reorganization Pioneer terminates the Subadvisory
Agreement with Oak Ridge without cause, equal to the greater of (a) $500,000
for each Subadvisory Agreement terminated or (b) twenty-four months' fees
payable under the relevant Subadvisory Agreement had the assets under
management in each fund been the same amount that they were at the time of
termination of the Subadvisory Agreement (based on assets as of November 30,
2004, this amount would be $589,256.05 for Pioneer Oak Ridge Small Cap Growth
Fund and $524,963.84 for Pioneer Oak Ridge Large Cap Growth Fund); provided that
all such fees shall not exceed $5 million in the aggregate with respect to both
Subadvisory Agreements, and (iii) Oak Ridge will be subject to certain
non-competition provisions.  The termination fee would not be triggered if a
Subadvisory Agreement is terminated by a fund or its shareholders with
or without cause.  The termination fee may create a potential conflict of
interest between a fund and Pioneer.  The termination fee could cause Pioneer to
recommend that a fund continue to engage Oak Ridge as the fund's subadviser
to avoid the fee in circumstances under which the appointment of a new
subadviser or the direct management of the fund by Pioneer may be in the
best interests of the fund.  While underperformance of a fund may permit Pioneer
to terminate Oak Ridge for cause and avoid the termination fee, the fund must
substantially underperform relative to its peer group for three years in order
for cause due to underperformance to exist.  While these potential conflicts of
interest could arise, the board of trustees of a fund does not intend to
consider the potential for Pioneer incurring a termination fee in evaluating
whether to continue Oak Ridge's appointment as subadviser to the fund.  The
provisions of the termination fee were disclosed to the board of trustees of
each fund prior to their approval of the relevant Subadvisory Agreement.
The terms of the Subadvisory Agreement with Oak Ridge are discussed in the
section "Investment Subadviser."

         The staff's comments and the Funds' responses will be reflected in an
amendment to each Fund's Registration Statement that will be filed pursuant
to 485(b) under the 1933 Act.

         Per the staff of the Commission's request and pursuant to th
Commission's press release ("SEC Staff to Publicly Release Comment Letters
and Responses," 2004-89), the Funds acknowledge the following:

o    Each Fund is responsible for the adequacy and accuracy of the disclosure
     in its filings;



Securities and Exchange Commission

o     Staff comments or changes to disclosure in response to staff comment
      in the filings reviewed by the staff do not foreclose the Commission
      from taking any action with respect to the filings; and
o     The Funds may not assert staff comments as a defense in any proceeding
      initiated by the Commission or any person under the federal securitie
      laws of the United States.

         If you have any questions or comments on the Registration Statement,
please contact either Elaina Kim at (617) 526-6685 (collect) or me at
(617) 526-6372 (collect), counsel to the Funds.


Very truly yours,
