ITEM 7.   FINANCIAL STATEMENTS AND EXHIBITS.

(c)      Exhibits

EXHIBIT NO.        DESCRIPTION
---------------    -------------------------------------------------------------
99.1               Press Release issued April 29, 2004, with respect to:
                   --      Financial results for Gartner, Inc. (the
                        "Company")  for the quarter ended March 31, 2004; and
                   --      The  announcement  that Michael  Fleisher,  Chairman
                        and CEO, intends to leave the Company.



ITEM 12. RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

On April 29, 2004, Gartner, Inc. announced financial results for the quarter
ended March 31, 2004. A copy of the Company's press release is furnished
herewith as Exhibit 99.1 and is incorporated herein by reference. The
information contained in this report shall not be incorporated by reference into
any filing of Gartner, Inc. with the SEC, whether made before or after the date
hereof, regardless of any general incorporation language in such filings.

The press release issued by the Company and furnished herewith as Exhibit 99.1
contains a non-GAAP financial measure. For purposes of the Securities and
Exchange Commission's Regulation G, a non-GAAP financial measure is a numerical
measure of a company's performance, financial position, or cash flows that
either excludes or includes amounts that are not normally excluded or included
in the most directly comparable measure calculated and presented in accordance
with accounting principles generally accepted in the United States ("GAAP"). In
the attached press release, Gartner, Inc. uses the non-GAAP measure of
normalized EPS. This non-GAAP financial measure is provided to enhance the
reader's overall understanding of Gartner's current financial performance and
prospects for the future. Gartner believes normalized EPS is an important
measure of Gartner's recurring operations as it excludes items that may not be
indicative of our core operating results. These measures however should be
considered in addition to and not as a substitute for, or superior to other
measures of financial performance prepared in accordance with GAAP. Normalized
EPS is based on net income (loss), excluding other charges, income from
investments, goodwill impairment and other non-cash charges. Normalized EPS for
2003 also includes the effect of the convertible debt as if it had been
converted at the beginning of 2003. In the attached press release, a
reconciliation of normalized net income and normalized EPS to GAAP net income
(loss) and GAAP net income (loss) per share is provided under "Supplemental
Information" at the end of the release.
