| Expense Narrative [Text Block] | oef_ExpenseNarrativeTextBlock | This table describes the fees and expenses that you may pay if you buy, hold, and sell Fund shares. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in this table and examples below. |

| Expense Example [Heading] | oef_ExpenseExampleHeading | EXAMPLE |
| Expense Example Narrative [Text Block] | oef_ExpenseExampleNarrativeTextBlock | This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. |

| Portfolio Turnover [Heading] | oef_PortfolioTurnoverHeading | PORTFOLIO TURNOVER |
| Portfolio Turnover [Text Block] | oef_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 69% of the average value of its portfolio. |

| Strategy [Heading] | oef_StrategyHeading | Principal Investment Strategies |
| Strategy Narrative [Text Block] | oef_StrategyNarrativeTextBlock | Under normal circumstances, the U.S. Managed Volatility Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in equity securities of U.S. companies of all capitalization ranges. These securities may include common stocks, preferred stocks, interests in real estate investment trusts (REITs), exchange-traded funds (ETFs) and warrants. The Fund may also, to a lesser extent, invest in American Depositary Receipts (ADRs) and securities of non-U.S. companies. The Fund uses a multi-manager approach, relying on a number of sub-advisers (each, a Sub-Adviser and collectively, the Sub-Advisers) with differing investment philosophies to manage portions of the Fund’s portfolio under the general supervision of SEI Investments Management Corporation (SIMC or the Adviser). The Fund seeks to achieve an absolute return of the broad U.S. equity markets, but with a lower absolute volatility. Over the long term, the Fund seeks to achieve a return similar to that of the Russell 3000 Index, but with a lower level of volatility. However, given that the Fund’s investment strategy focuses on absolute return and risk, the Fund’s sector and market capitalization exposures will typically vary from the index and may cause significant performance deviations relative to the index over shorter-term periods. The Fund seeks to achieve lower volatility by constructing a portfolio of securities that effectively weighs securities based on their total expected risk and return, without regard to market capitalization and industry. Due to its investment strategy, the Fund may buy and sell securities and other instruments frequently. |

| SIIT U.S. Managed Volatility Fund | U.S. MANAGED VOLATILITY FUND | Market Risk [Member] | ||
| Prospectus [Line Items] | oef_ProspectusLineItems | |
| Risk [Text Block] | oef_RiskTextBlock | Market Risk — The risk that the market value of a security may move up and down, sometimes rapidly and unpredictably. Market risk may affect a single issuer, an industry, a sector or the equity market as a whole. Equity markets may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Similarly, environmental and public health risks, such as natural disasters, epidemics, pandemics or widespread fear that such events may occur, may impact markets adversely and cause market volatility in both the short- and long-term. |
| SIIT U.S. Managed Volatility Fund | U.S. MANAGED VOLATILITY FUND | Large Capitalization Risk [Member] | ||
| Prospectus [Line Items] | oef_ProspectusLineItems | |
| Risk [Text Block] | oef_RiskTextBlock | Large Capitalization Risk — The risk that larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies. |
| SIIT U.S. Managed Volatility Fund | U.S. MANAGED VOLATILITY FUND | Small and Medium Capitalization Risk [Member] | ||
| Prospectus [Line Items] | oef_ProspectusLineItems | |
| Risk [Text Block] | oef_RiskTextBlock | Small and Medium Capitalization Risk — The risk that small and medium capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small and medium capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, small capitalization and medium capitalization stocks may be more volatile than those of larger companies. Small capitalization and medium capitalization stocks may be traded over-the-counter (OTC). OTC stocks may trade less frequently and in smaller volume than exchange listed stocks and may have more price volatility than that of exchange-listed stocks. |
| SIIT U.S. Managed Volatility Fund | U.S. MANAGED VOLATILITY FUND | Investment Style Risk [Member] | ||
| Prospectus [Line Items] | oef_ProspectusLineItems | |
| Risk [Text Block] | oef_RiskTextBlock | Investment Style Risk — The risk that equity securities of U.S. companies of all capitalization ranges may underperform other segments of the equity markets or the equity markets as a whole. |
| SIIT U.S. Managed Volatility Fund | U.S. MANAGED VOLATILITY FUND | Preferred Stock Risk [Member] | ||
| Prospectus [Line Items] | oef_ProspectusLineItems | |
| Risk [Text Block] | oef_RiskTextBlock | Preferred Stock Risk — Preferred stock represents an equity or ownership interest in an issuer that pays dividends at a specified rate and that has precedence over common stock in the payment of dividends. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds take precedence over the claims of those who own preferred and common stock. |
| SIIT U.S. Managed Volatility Fund | U.S. MANAGED VOLATILITY FUND | REITs Risk [Member] | ||
| Prospectus [Line Items] | oef_ProspectusLineItems | |
| Risk [Text Block] | oef_RiskTextBlock | REITs Risk — REITs are trusts that invest primarily in commercial real estate or real estate-related loans. The Fund’s investments in REITs will be subject to the risks associated with the direct ownership of real estate. Risks commonly associated with the direct ownership of real estate include fluctuations in the value of underlying properties, defaults by borrowers or tenants, changes in interest rates and risks related to general or local economic conditions. Some REITs may have limited diversification and may be subject to risks inherent in financing a limited number of properties. |
| SIIT U.S. Managed Volatility Fund | U.S. MANAGED VOLATILITY FUND | Exchange-Traded Funds Risk [Member] | ||
| Prospectus [Line Items] | oef_ProspectusLineItems | |
| Risk [Text Block] | oef_RiskTextBlock | Exchange-Traded Funds Risk — The risks of owning shares of an ETF generally reflect the risks of owning the underlying securities the ETF is designed to track, although lack of liquidity in an ETF could result in its value being more volatile than the underlying portfolio securities. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. |
| SIIT U.S. Managed Volatility Fund | U.S. MANAGED VOLATILITY FUND | Warrants Risk [Member] | ||
| Prospectus [Line Items] | oef_ProspectusLineItems | |
| Risk [Text Block] | oef_RiskTextBlock | Warrants Risk — Warrants are instruments that entitle the holder to buy an equity security at a specific price for a specific period of time. Warrants may be more speculative than other types of investments. The price of a warrant may be more volatile than the price of its underlying security, and a warrant may offer greater potential for capital appreciation as well as capital loss. A warrant ceases to have value if it is not exercised prior to its expiration date. |
| SIIT U.S. Managed Volatility Fund | U.S. MANAGED VOLATILITY FUND | American Depositary Receipts (ADRs) Risk [Member] | ||
| Prospectus [Line Items] | oef_ProspectusLineItems | |
| Risk [Text Block] | oef_RiskTextBlock | American Depositary Receipts (ADRs) Risk — ADRs are certificates evidencing ownership of shares of a foreign issuer that are issued by depositary banks and generally trade on an established market. ADRs are subject to many of the risks associated with investing directly in foreign securities, including, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments. |
| SIIT U.S. Managed Volatility Fund | U.S. MANAGED VOLATILITY FUND | Liquidity Risk [Member] | ||
| Prospectus [Line Items] | oef_ProspectusLineItems | |
| Risk [Text Block] | oef_RiskTextBlock | Liquidity Risk — The risk that certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to lower the price of the security, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Fund management or performance. |

| Prospectus [Line Items] | oef_ProspectusLineItems | |
| Risk [Text Block] | oef_RiskTextBlock | Foreign Investment Risk — The risk that non-U.S. securities may be subject to additional risks due to, among other things, political, social and economic developments abroad, currency movements, and different legal, regulatory, tax, accounting and audit environments. |
| SIIT U.S. Managed Volatility Fund | U.S. MANAGED VOLATILITY FUND | Portfolio Turnover Risk [Member] | ||
| Prospectus [Line Items] | oef_ProspectusLineItems | |
| Risk [Text Block] | oef_RiskTextBlock | Portfolio Turnover Risk — Due to its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and taxes subject to ordinary income tax rates as opposed to more favorable capital gains rates, which may affect the Fund’s performance. |
