PGIM Quant Solutions Mid-Cap Index Fund Investment Risks - PGIM Quant Solutions Mid-Cap Index Fund	Jul. 31, 2026
Economic And Market Events Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Economic and Market Events Risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth or the functioning of the securities markets, or otherwise reduce inflation, may at times result in unusually high market volatility, which could negatively impact performance. Governmental efforts to curb inflation often have negative effects on the level of economic activity. Relatively reduced liquidity in credit and fixed income markets could adversely affect issuers worldwide.
Equity And Equity Related Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Equity and Equity-Related Securities Risk. Equity and equity-related securities may be subject to changes in value, and their values may be more volatile than those of other asset classes. In addition to an individual security losing value, the value of the equity markets or a sector in which the Fund invests could go down. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments.
Exchange Traded Funds ETF Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Exchange-Traded Funds (“ETFs”) Risk. Investing in securities issued by ETFs involves risks similar to those of investing directly in the securities and other assets held by the ETF. Unlike shares of typical mutual funds, shares of ETFs are generally traded on an exchange throughout a trading day and bought and sold based on market values and not at net asset value. For this reason, shares could trade at either a premium or discount to net asset value, which may be substantial during periods of market stress. The trading price of an index-based ETF is expected to (but may not) closely track the net asset value of the ETF, and the Fund will generally gain or lose value consistent with the performance of the ETF’s portfolio securities. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs. In addition, the Fund will indirectly bear its pro rata share of the fees and expenses incurred by an ETF (including ETFs managed by the Manager or the subadviser(s)) in which it invests, including advisory fees (to the extent not offset by the Manager through waivers). These expenses are in addition to the advisory and other expenses that the Fund bears directly in connection with its own operations. An index-based ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons.
Fund Of Funds Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Fund of Funds Risk. The Fund is an investment option for other PGIM Investments-advised mutual funds that are managed as “funds of funds.” As a result, from time to time, the Fund may experience relatively large redemptions and could be required to liquidate its assets at inopportune times or at a loss or depressed value, which could cause the value of your investment to decline.
Increase In Expenses Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Increase in Expenses Risk. Your actual cost of investing in the Fund may be higher than the expenses shown in the expense table for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile. Active and frequent trading of Fund securities can increase expenses.
Index Investment Approach Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Index Investment Approach Risk. Since the Fund is passively managed, assets are not allocated from one stock or group of stocks to another based on their prospects, or from stocks into bonds or cash equivalents in an attempt to cushion the impact of a market decline. As a result, the Fund’s performance may be less favorable than that of a portfolio using an active investment strategy. There is no guarantee that the Fund's investment results will have a high degree of correlation to those of the Index. The Fund’s expenses, changes in securities markets, changes in the composition of the Index, errors in index provider data, and the timing of purchases and redemptions of Fund shares, among other things, may affect the correlation between Fund and Index performance. The Fund may not perform as well as other investments if, among other things, the Index declines or performs poorly relative to other related indexes or individual securities or the securities issued by companies that comprise the Index fall out of favor with investors.
Large Shareholder And Large Scale Redemption Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Large Shareholder and Large Scale Redemption Risk. Certain individuals, accounts, funds (including funds affiliated with the Manager) or institutions, including the Manager and its affiliates, may from time to time own or control a substantial amount of the Fund’s shares. There is no requirement that these entities maintain their investment in the Fund. There is a risk that such large shareholders or that the Fund’s shareholders generally may redeem all or a substantial portion of their investments in the Fund in a short period of time, which could have a significant negative impact on the Fund’s NAV, liquidity, and brokerage costs. Large redemptions could also result in tax consequences to shareholders and impact the Fund’s ability to implement its investment strategy. The Fund’s ability to pursue its investment objective after one or more large scale redemptions may be impaired and, as a result, the Fund may invest a larger portion of its assets in cash or cash equivalents.
Market Disruption And Geopolitical Risks [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Disruption and Geopolitical Risks. Market disruption can be caused by economic, financial or political events and factors, including but not limited to, international wars or conflicts (including the U.S. and Israeli military operation against Iran, Russia’s military invasion of Ukraine and the Israel-Hamas war), geopolitical developments (including trading and tariff arrangements, sanctions and cybersecurity attacks), instability in regions such as the Middle East, South America, Eastern Europe, and Asia, terrorism, natural disasters and public health epidemics (including the outbreak of COVID-19 globally). Recent policy decisions of the U.S. government and governments of foreign countries may increase geopolitical risks that could adversely affect the investment performance of the Fund. These policies have the potential to impact international relations, trade agreements and the overall regulatory environment in ways that could create uncertainty and instability in domestic and global markets. Actions taken by the U.S. government and governments of foreign countries in respect of international trade relations could lead to trade wars, increased costs for imported goods, disruptions in supply chains, reduced foreign investment, and instability in regions where the Fund invests. The risk of such events has meaningfully increased in recent periods due to heightened international tensions stemming from rivalry among the world’s dominant economic and military powers. The extent and duration of such events and resulting market disruptions cannot be predicted, but could be substantial and could magnify the impact of other risks to the Fund. These and other similar events could adversely affect the U.S. and foreign financial markets and lead to increased market volatility, reduced liquidity in the securities markets, significant negative impacts on issuers and the markets for certain securities and commodities and/or government intervention. They may also cause short- or long-term economic uncertainties in the United States and worldwide. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the Fund’s investments may be negatively impacted. Further, due to closures of certain markets and restrictions on trading certain securities, the value of certain securities held by the Fund could be significantly impacted, which could lead to such securities being valued at zero.
Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Risk. Securities markets may be volatile and the market prices of the Fund’s securities may decline. Securities fluctuate in price based on changes in an issuer’s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline.
Medium Capitalization Mid Cap Company Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Medium Capitalization (Mid-Cap) Company Risk. The Fund’s investments in mid-cap companies carry more risk than investments in larger capitalized companies. Investments in mid-cap companies carry additional risks because earnings of these companies tend to be less predictable; they often have limited product lines, markets, distribution channels or financial resources; and the management of such companies may be dependent on one or a few key people. The market movements of these companies’ securities may be more abrupt or erratic than the market movements of securities of larger, more established companies or the stock market in general. Historically, mid-cap companies have sometimes gone through extended periods when they did not perform as well as larger companies. Mid-cap companies generally are comparatively less liquid than larger companies, which may make such investments more difficult to sell at the time and price that the Fund would like. Also, the stocks of mid-cap companies may fall out of favor relative to those of small- or large-capitalization companies, causing the Fund to underperform other equity funds that focus on small- or large-capitalization companies.
Sector Exposure Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Sector Exposure Risk. From time to time the Fund may invest a significant portion of its assets in companies within one or more economic sectors. Issuers within an economic sector may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.
Tracking Error Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Index, pricing differences, transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of distributions, tax gains or losses, changes to the Index or the need to meet various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.
Risk Lose Money [Member]
Prospectus [Line Items]
Risk [Text Block]	You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments.
Risk Not Insured Depository Institution [Member]
Prospectus [Line Items]
Risk [Text Block]	An investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; and is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
