(Recasts, adds analyst comments, more detail, shares)

LONDON, Oct 22 (Reuters) - Publisher Pearson has raised its full-year sales forecast for its professional education business and said third-quarter trading had been strong across the group, particularly in the United States.

Analysts reacted positively to the update on third-quarter and nine-month trading and an upbeat outlook for education published on Monday, given there had been concerns about Pearson's exposure to a weakening U.S economy. Pearson (PSON.L: Quote, Profile, Research, Stock Buzz) generates around two-thirds of its sales in the United States.

"Whilst not completely immune from a downturn, we remain confident the education assets will be relatively resilient and the results today should reassure the market," said UBS.

Shares in Pearson were up 0.5 percent at 769 pence at 0826 GMT while the FTSE 100 .FTSE was more than 1 percent lower.

Pearson, which also publishes Penguin books and the Financial Times newspaper, raised its projection for full-year sales growth in its professional education division to 8 to 10 percent from 5 to 7 percent previously.

The unit's sales rose 12 percent in the nine months and further margin improvement is anticipated, Pearson said, amid ongoing strong demand for its professional certifications in areas such as graduate management, nursing and driving tests.

At a group level, Pearson said trading was strong in the third quarter and that underlying sales and operating profit rose 6 and 20 percent respectively over the first nine months.
