           THE McGRAW-HILL COMPANIES STRENGTHENS CORE GROWTH PLATFORMS

                       Updates Earnings Guidance For 2005

    NEW YORK, March 9 /PRNewswire-FirstCall/ -- The McGraw-Hill Companies (NYSE:
MHP) is using strategic acquisitions and partnerships to strengthen its
platforms for growth in each of the three major markets it serves -- financial
services, education, and information and media services, said Harold McGraw III,
Chairman, President and CEO of The McGraw-Hill Companies, at Merrill Lynch's
Annual Advertising/Marketing, Education & Information Conference.

    "It is our objective to grow in our core markets organically and by
judiciously making strategic acquisitions to expand our opportunities," Mr.
McGraw said. "The Corporation's strong cash flow has enabled us to fund an
increased dividend, repurchase shares and make operating investments and
strategic acquisitions."

    He cited the acquisitions in 2004 of The Grow Network, which has
strengthened the Corporation's position in testing, assessment and reporting, an
important growth area in the education market; and of Capital IQ, which is
bringing new revenue and a technology platform that will transform Standard &
Poor's data and distribution services.

    Mr. McGraw said acquisitions are also playing a role in driving global
growth, a key priority for the Corporation. It continues to make strategic
investments to improve its prospects, particularly in the financial services
segment and in the Asia/Pacific region. "Last month, Standard & Poor's improved
its ability to serve the Australian market by acquiring ASSIRT, a leading
provider of fund data, ratings of Australian managed funds and research," he
said.

    "S&P is also making other additions to a well established global network
that it created in the world's leading financial capitals during the 1990s. S&P
announced last month that it is seeking to increase its ownership of CRISIL,
India's leading provider of credit ratings. S&P has been working with CRISIL
since 1996 and currently owns approximately 10%. A majority position would
enable S&P to integrate CRISIL more fully into our operations and allow for more
collaboration across a broad range of activities. In addition, S&P signed an
affiliation agreement last month with Malaysia's leading rating agency, Rating
Agency Malaysia Berhad."

    "To expand S&P's platform in independent equity research and tap the
increased buy-side demand for primary research services, the Corporation signed
an agreement last week to acquire Vista Research. The acquisition is subject to
NASD approval and is expected to close in early April."

    In business information, Mr. McGraw said, "We took an important step earlier
this week by signing an agreement to acquire J.D. Power and Associates, a
leading provider of marketing information to consumers and businesses worldwide.
The J.D. Power brand is enormously respected in the global automotive industry
and it has established a strong and growing presence in other key industries.

    J.D. Power shares our core values, brings complementary strengths and will
benefit from our global presence and detailed knowledge of major industries,
including financial services, construction, energy, aviation and healthcare. We
expect the transaction, which is subject to Hart-Scott-Rodino regulatory review,
to close in April."



    "For the acquisitions we have announced in 2005 - ASSIRT, Vista and J.D.
Power -- we will spend approximately $420 million in cash. When the new
acquisitions close next month, they will dilute our earnings per share this year
by 6 to 7 cents, of which about 4 to 5 cents will hit in the second quarter,
primarily because of J. D. Power's seasonality; it is a strong second-half
business. The impact in 2006 will be substantially less - about 3 cents - and
will be cash positive."

    In view of the dilution in 2005, Mr. McGraw adjusted the Corporation's
earnings guidance. "Originally, we expected double-digit growth in earnings per
share in 2005 from continuing operations, including 10-to-12 cents dilution from
acquisitions last year and changes in the pension plan assumptions for 2005, but
excluding the 2004 non-cash benefit of 10 cents per share from accrued tax
liabilities and a change in accounting for share-based compensation effective
July 1."

    "Now, we expect high single-digit growth in earnings per share from
continuing operations, including 16-to-19 cents of dilution from acquisitions -
from 2004 and the newly announced acquisitions for 2005 -- and changes in the
pension plan assumptions for 2005, but excluding the 2004 non-cash benefit of 10
cents from accrued tax liabilities and a change in accounting for share-based
compensation effective on July 1."

    Mr. McGraw said, "The McGraw-Hill Companies continues to aspire to
double-digit growth in earnings per share in 2005."

    "We are committed to advancing total shareholder return. Since 1996, we have
returned nearly $3.2 billion to shareholders through share repurchases and
dividends. That's a compounded annual growth rate of 16% for the last eight
years. For the last 10 years, the last five and the last three years, and in
2004, our total return has outpaced the S&P 500. We are committed to continue
building on our record in 2005."

    The forward-looking statements in this news release involve risks and
uncertainties and are subject to change based on various important factors,
including worldwide economic, financial, political and regulatory conditions,
the health of capital and equity markets, including possible future interest
rate changes, the pace of recovery in the economy and in advertising, the level
of expenditures in the education market, the successful marketing of competitive
products and the effect of competitive products and pricing.
