                 First Quarter Earnings Per Share of 39 Cents

                            Revenue Grows by 9.7%
                 Operating Margin Improves in All 3 Segments

    NEW YORK, April 27 /PRNewswire-FirstCall/ -- The McGraw-Hill Companies
(NYSE: MHP) today reported diluted earnings per share of 39 cents from net
income for the first quarter of 2004.  The results include a one-time non-cash
benefit of $20 million, or 10 cents per share, of accrued tax liabilities
following the completion of various federal, state, local and foreign tax
audits.  This compares to the first quarter 2003 diluted earnings per share
from net income of 50 cents, which included an after-tax impact of 29 cents
from discontinued operations last year.
    Income from continuing operations for the first quarter of 2004 increased
91.3% to $76.3 million.  Net income for the first quarter of 2004 was $75.7
million.
    Revenue for the first quarter of 2004 increased 9.7% to $911.6 million.
    "We gained momentum late in the first quarter and finished with a very
solid performance," said Harold McGraw III, chairman, president and chief
executive officer of The McGraw-Hill Companies.  "Buoyed by a surge of
financing in March, Financial Services produced a record first quarter.  We
also saw pickups in education and advertising and benefited from rigorous cost
controls.
    Education:  "Revenue for the segment increased 6.4% to $278.2 million and
the operating loss was reduced by 2.0% to $68.8 million in the first quarter
compared to the same period last year.  Favorable foreign exchange rates
contributed $6.1 million to revenue and had a slightly negative impact on
operating profits.
    "Revenue for the McGraw-Hill School Education Group grew by 8.6% to $125.1
million in the first quarter.  Revenue for the McGraw-Hill Higher Education,
Professional and International Group increased by 4.7% to $153.1 million.
    "Growth in reading and testing markets was key to the McGraw-Hill School
Education Group's improved performance in a seasonally slow quarter for
education.  The federal No Child Left Behind Act signed into law in 2002
placed new emphasis on teaching reading in the early years.  As a result,
educators are now acquiring reading preparation materials for the pre-K
market, new programs for grades K-3 and remedial products for grades 4-6.
Some of the funding for our material came from Reading First and Early Reading
First programs, which are part of the No Child Left Behind Act.
    "We continue to benefit from the increased emphasis on testing as states
prepare to meet mandatory federal requirements to test annually every child in
grades 3 through 8 in reading and math beginning in the 2005-06 school year.
Custom-contract revenue improved in California, Wisconsin, Connecticut, West
Virginia, Colorado and Maryland, but expenses increased because of additional
scoring requirements for some state contracts.  We also won a new statewide
contract for Arizona.
    "Sales in higher education markets here and abroad offset softness in
professional titles in the first quarter.  School products also contributed to
improved international sales in Latin America, the United Kingdom and Canada.
    "In the U.S. college and university market, key titles in the first
quarter were:
      * Bodi, Investments, 6/e
      * Nickels, Understanding Business, 7/e
      * Block, Foundations of Financial Management, 11/e
    "Imprints in science, engineering and mathematics also contributed to the
first quarter gain.
    Financial Services:  "Revenue for this segment increased 15.6% to $456.6
million and operating profits grew by 19.9% to $173.8 million in the first
quarter versus last year.  Favorable foreign exchange rates contributed $9.7
million to revenue and had a slightly negative impact on operating profit in
the first quarter.
    "Strong structured finance and high-yield corporate markets here and
abroad as well as solid growth in counterparty credit ratings and rating
evaluation services all contributed to Standard & Poor's outstanding results.
International ratings accounted for nearly 35% of ratings revenue and grew
faster than domestic operations.
    "Corporate and structured financing activity surged late in the first
quarter.  Typically, there is a pickup in structured finance during the final
month of each quarter, but action this year was particularly heavy late in
March in the residential mortgage-backed securities market.  There also was
good growth in other asset classes, including commercial mortgage-backed
securities and collateralized debt obligations.
    "New issue dollar volume grew in the United States and in European bond
markets in the first quarter versus the same period in 2003.  In the U.S., new
issue dollar volume was up 10.4%.  Corporate new issuance increased 9.1%.
Public finance declined by 5.5%.  Mortgage-backed issuance was up 29.6%, while
asset-backed issuance declined 12.2%, according to reports from Securities
Data Corporation and Harrison Scott Publications.
    "In Europe, new issue dollar volume soared by 42.1%, according to
Securities Data Corporation and Harrison Scott Publications.
    "Demand for retail and brokerage information is recovering slowly, but
sales of products and services to institutional clients picked up as
conditions in financial markets continued to improve.  Assets under management
for Exchange-Traded Funds based on S&P indexes climbed to $81.3 billion at the
end of March, a 34.6% increase over the first quarter of 2003.
    "Valuation services improved, reflecting growing merger and acquisition
activity and continued growth in non-valuation services in real estate and
litigation support.

    Information and Media Services:  "Revenue for this segment increased 1.3%
to $176.7 million and operating profits, reflecting effective cost containment
efforts, grew by 9.4% to $13.7 million in the first quarter versus the same
period last year.
    At the Business-to-Business Group, which includes BusinessWeek,
construction, energy, aviation and healthcare products and services, revenue
was up 0.6% to $152.0 million for the first quarter.
    "After a slow start, advertising pages in BusinessWeek increased 11.8% in
March enabling the publication to finish the first quarter with a year-over-
year gain of 2.6%, according to the Publishers Information Bureau.
    "Conferences and shows contributed to improvement in aviation and energy,
where information products also benefited from increased volatility in the oil
and gas markets.  The McGraw-Hill Construction Network, launched late in 2003,
continues to gain momentum but could not offset softness in advertising in the
publications serving the construction market.
    "For the Broadcasting Group, revenue increased 5.8% to $24.7 million in
the first quarter as strong political advertising helped offset the absence of
the Super Bowl, which had been aired on ABC in 2003.
    The outlook:  "We're pleased with the good start in 2004 from our three
segments, even though the first quarter is by far our smallest each year.  On
a full year basis, we still face the lightest adoption calendar of the decade
in the elementary-high school market, somewhat tougher comparisons in
Financial Services and an anticipated decline in the issuance of residential
mortgage-backed securities.
    "Despite these market issues, our full year guidance remains unchanged.
We continue to project income from continuing operations to increase in the
mid-to-high single digits in 2004 without the reoccurrence of the 30-cent
after-tax benefit from the sale of the equity interest in Rock-McGraw, Inc."
